        <p>Live music concert analysis provides an opportunity to explore cultural and historical trends. The art of set-list construction, of which songs to play, has many considerations for an artist, and the notion of how much variety diferent artists play is an interesting topic. Online communities provide rich crowd-sourced encyclopaedic data repositories of live concert set-list data, facilitating the potential for quantitative analysis of live music concerts. In this paper, we explore data acquisition and processing of musical artists' tour histories and propose an approach to analyse and explore the notion of variety, at individual tour level, at artist career level, and for comparisons between a corpus of artists from diferent musical genres. We propose notions of a shelf and a tail as a means to help explore tour variety and explore how they can be utilised to help define a single metric of variety at tour level, and artist level. Our analysis highlights the wide diversity among artists in terms of their inclinations toward variety, whilst correlation analysis demonstrates how our measure of variety remains robust across difering artist attributes, such as the number of tours and show lengths.</p>

      <title>1. Introduction</title>
      <p>tially impact and influence listening behaviour of an artist’s fans regarding non-live material
[30].</p>
      <p>The process of set-list creation varies, with some artists meticulously planning their sets in
advance, while others prefer to make more spontaneous decisions based on the energy and
reactions of the crowd during the show. Getting the right balance of set-list variety is crucial.
Artists may face backlash if their set-lists are perceived as too formulaic and lacking in variety.
For example, during Bruce Springsteen’s 2023 tour, fans criticised performances for being too
similar night after night, leading band members to defend their choices on social medi2a5][.
Conversely, there is a risk of alienating fans by including too many unexpected songs at the
expense of beloved greatest hits, as seen by some fan’s reactions to recent Bob Dylan shows
[13], or by altering hit songs too much from their album versions, as seen by fan frustrations at
recent Arctic Monkeys’ shows 7[]. Constructing a set list involves navigating diverse
expectations, and the degree of variety in an artist’s performances is an intriguing topic with broader
applications, such as historical live performance recommender system1]s. [</p>
      <p>In this paper, we explore the data acquisition and processing of musical artists’ tour histories,
and propose an approach to explore variety, at individual tour level, artist career level, and for
comparisons between a corpus of artists. For this, we propose notions of a shelf and a tail, as
a means to investigate and explore tours’ variety and properties, and explore how they can be
used to quantify variety at tour level and artist level. Additionally, our approach explores the
impact of cover songs upon variety, and explores variety comparisons across musical genres.</p>
      <p>Through analysing many artists, we highlight the wide range of artist variety levels, from
those who tend to focus more on greatest hits to those who perform more diverse shows
featuring deep cuts, and everything in between. Additional correlation analysis of our concept of
variety explores how our measure remains robust across artists with difering characteristics,
such as the number of tours or average show lengths. For more information about the project
and its data, see the project’sGitHub repositor,y3 and to interactively explore the data and the
proposed approach, see the project’Isnteractive Web App4.</p>

      <title>2. Background</title>
      <p>Work has explored live music performance exploring performer or audience psychology and
touching on how set-lists impact this, such as in terms of presence and representation within
shows and set-lists [27], through measuring value of live music as a motivation scal2e3][,
and exploring how the set-list and beyond has a bearing on an artist’s impact as part of their
stage success [10]. Other work has explored live music performances from the perspective of
music theory, such as work defining performance parameters in relation to how performances
bring compositions to life through variations in timing and dynamics and its impact on listener
perception [19], and work exploring how composers’ choices in tones, intervals, and harmonies
influence stylistic music changes over time [22].</p>

        <p>
          Various work exploring live music performance taking a more quantitative approach have
focused on an in-depth analysis of a single artist. Work has explored the band The Grateful
Dead, examining the band’s live recordings over three decades to analyse the performances in
relation to cultural trends in music and to investigate how the performances of the band change
over time [
          <xref ref-type="bibr" rid="ref5">33</xref>
          ]. Others have analysed The Grateful Dead’s live concerts from 1972 to 1995 in
comparison to listening habits outside of concert3s0[], highlighting how there are correlations
between live set-lists and home listening. Work focusing on the artist Bruce Springsteen, has
explored his live performances and set-lists from the perspective of examining how set-list
analysis can provide inclinations about tensions between commercial considerations for
playing new album material and playing expected but older hi2ts].[Bob Dylan is another artist
work has focused upon, such as a study of Bob Dylan’s set-lists from the 1960s to the 2020 that
investigates his approach to performing, exploring how he curates a show and how this in turn
creates a meta-narrative 8[].
        </p>
        <p>
          Limited studies have looked to compare tour and set-lists for multiple artists. The Music &amp;
Entertainment publication Consequence set out and discussed the ”25 Best Rock Acts with the
most Unique set-lists” [
          <xref ref-type="bibr" rid="ref3">31</xref>
          ]. Within such articles, although there is an implication of a focus,
here on the acts whose shows define the word unique, the methodology involved in compiling
such a list is obscured, and so therefore it is difÏcult to assess.
        </p>
        <p>Some recent discourse has explored how the make up of fan communities of artists such
as Taylor Swift and The Grateful Dead may share surprising similarities, despite their
diferent musical styles, and the impact this can have on further similarities between performance
set-lists [5]. The notion of a comparison between Taylor Swift and The Grateful Dead
performances has been further explored, along with a limited number of other artists, in terms
of unique songs [11]. Focusing on considerations of the notion of special songs, analysis of
set-lists from individual tours for diferent artists is carried out, to explore the prominence
of unique (and quite unique) song occurrence rates. Comparisons highlight how The
Grateful Dead is seen as a very varied artist compared to Taylor Swift, when considering variety
only from the perspective of unique special ”surprise” songs. In this analysis, only individual
tours are considered, which may result in an unrepresentative view of an artist’s overall career.
Additionally, the methodology favours artists with longer tours and longer sets.</p>
        <p>The metric Consecutive Set Similarity (CSS) has been proposed to look to measure variety
for an artist 2[0]. Here, an artist’s career of set-lists are arranged in sequence and each set-list is
compared to the previous set-list in terms of the amount of diferent songs, resulting in a value
of 1 if the the set-list is identical to the previous set, and -1 if it is completely diferent. From this,
an overall average is derived for each artist, from which comparisons and clustering of diferent
artists can be performed2[8]. The measure has a very narrow focus due to only considering
two shows at a time, and so will consider oscillating changes of songs that are played frequently
but not every night as signalling high variety. Moreover, it does not consider information such
as when one tour ends and another begins (likely to signal a significant change in set-lists,
which may in turn favour artists with many small tours over a long period).</p>
        <p>Some coverage has highlighted how artists themselves explore the art of set-list curation,
and the considerations they have for variety. During a tour that contained over 800 shows the
band Radiohead made a conscious choice to ensure every show was unique and to never have a
repeating set-list. The band would curate the set-lists daily and emphasised the importance of
variety, contrasting their approach with other artist’s that play identical sets nigh2tl1y].[More
recently, it has been claimed that the band Metallica look to customise concert set-lists based
on local Spotify data (and local radio trends), to look to cater to localised fans’ preferences, and
to help increase show diversity2[9].</p>

      <title>3. Our Approach</title>
      <p>In our approach, raw artist tour data is first collected and processed, then utilized in various
stages of analysis, as illustrated in Figu1r.eCommunities such as MusicBrain5z and Setlist.fm6
provide extensive crowd-sourced encyclopaedic data on musical artists and live concert set-lists.
The following sub-section outlines our data acquisition process, detailing how these sources
were leveraged to obtain the data used for our analysis.</p>
      <sec id="sec-3-1">
        <title>3.1. Data Acquisition</title>
        <p>Given a set of music artist names, we acquire tour details, and data for each tour of each artist,
and store the data as depicted in the data model in Figur2e. For each artist name, they can
be uniquely identified via MusicBrainz Identifiers (MBIDs), which is a universal unambiguous
standard artist identification.7 Through calls to the Music Brainz AP8It,he MBID for each artist
name is acquired, along with additional Music Brainz artist information including their

der (one of Male, Female, or Group), and theSitrart Date and EndDate.9 Additionally, a single
musical genre considered most representative was curated for each artist using MusicBrainz’s
genre information. As this data often assigns multiple genre tags to an artist, a manual
selection of a single tag was performed where necessary. Next, using each artist’s MBIDs, each’s
corresponding setlist.fm ID (a separate setlist.fm unique identifier for each artist) is obtained
via calls to the setlist.fm AP1I0. This data is stored as depicted in the Artist table in Figu2r.e</p>
          <p>The determined single genres for each artist result in a large number of diferent genre values,
many representing similar sub-genres of a more general genre. To make genre analysis more
tractable, the set of genres can be mapped onto a smaller set of generalized genres. Such a
mapping of dozens of genres onto a set of generalized genres is shown in Tab1l.eThis data is
stored as depicted in the Genre table in Figur2e.11</p>
          <p>Given a set of artist setlist.fm IDs, a list of each artist’s tours can be obtained, from which
data associated with each tour of each artist can be subsequently acquired. For each tour,
overall information of the tour name, the total number of shows on the tour, and date ranges
are acquired, and stored as depicted in the Tour table in Figu2r.eFor each tour’s songs, the list
of songs played on the tour, along with each song’s number of plays on the tour are acquired.
Additionally, for each song, whether the song is denoted as a cover song (with respect to the
artist the tour is for) is recorde12d.The song information is stored as depicted in the Song table
9For groups this represents their formation date and disband dates, for solo artists it holds just their birth dates and
retirement or death dates. For ongoing artists EndDate will be ”present”.

11The assignment of a single genre to each artist, followed by the mapping of these genres to a broader set of
generalized categories, has been curated as a proof of concept. However, genre classification is a complex and expansive
subject in its own right, with numerous studies addressing the challenges associated with genre categorisation
[9] and the phenomenon of genre crossover3[2]. Given such complexities, the automation of genre classification
represents a compelling area for future exploration.
12Additionally, tours that are empty (made up of only empty shows) are removed, as are any artists for which all

          <p>From this, full artist tour history data for over 200 artists was acquired, chosen for their
prominence within popular music history and culture. This number is progressively expanding,
and up-to-date figures, and access to the data, can be found at the project’sGitHub repository1.3
All of the data acquired is stored as raw data, as depicted in Figu1,rteo then be utilised within
the analysis stage.</p>

        <title>3.2. Data Pre-Processing</title>
        <p>Before beginning analysis, pre-processing of the raw dataset is performed. Within our
analysis, we are interested in artists who have sufÏciently substantial touring histories. Therefore,
we define thresholds to utilise only artists that have a minimum number of tours and a
minimum overall number of shows, and only keep tours that have a minimum number of shows,
a minimum number of unique songs played on the tour, and a minimum show length of the
tours are empty. Further, tours identified by their name as a set of Promotional publicity media/private shows,
are removed.

shows from the tour1.4 These threshold values are inherently subjective and context dependent;
therefore, we conduct the analysis on the raw data, preserving its integrity so that alternative
thresholds could be applied if needed. Within our analysis that follows, the threshold
parameter values utilised are shown in Tabl2e. Following the pre-processing stage, we begin the
analysis at individual tour level.</p>
      </sec>
      <sec id="sec-3-3">
        <title>3.3. Tour Analysis</title>
        <p>For a tour, each (unique) song has a Play Count ( ), denoting how many times it was played
on that tour. Tours can vary in terms of how many shows they are made up of, therefore, for
comparisons between tours, a tour’s (absolute) values can be normalised with respect to
the number of shows in the tour. For a tour, a Relative Play Count ( ) for each song played
on the tour can be computed via:

 = ( PC ) ∗ 100

(1)
Where   is the  value of the -th song and  is the number of shows in the tour. A
 value of 100 represents a song being played every single show of a tour, whilst a value
of 50 represents a song being played at exactly half of the tour’s shows. We can visualise a
tour and its songs in terms of their values, where the y-axis denote s value, and the
x-axis denotes song number where songs are sorted with respect to values high to low.
For example, Bruce Springsteen (and the E-Street Band’s) 2023 tour, is shown in Figu3rae,and
Coldplay’s Music of the Spheres 2023 Tour is shown in Figu3rbe. Such tour visualisations
highlight a generality for many tours to map out an s shaped sigmoidal like function shape.
From a tour’s dataset, notions oSfhelf, Tail, 100%’ers, Uniques and Covers can be calculated and
subsequently highlighted within such visualisations. Each of these notions are defined and
explained next.</p>
        <p>Shelf - The notion of a tour’sShelf is a measure of the significance of a tour to have a set of
of songs that are played at most of the tour’s shows, and outline a shelf like shape in the top
left of the plots in Figure 3. Given a Shelf Size ( ) value, denoting what top percentile of tour
songs are to be considered part of the shelf, a Shelf Val uecan be calculated as the ratio of a
14Such thresholds are beneficial for identifying and removing tours with missing data issues, such as tours which
only a few of the shows have been added for, or tours that have many shows added but lack song information for
many of the shows. Such tours, if left in the data, can unduly impact and bias analysis.

that are played only rarely on the tour, and outlines a tail like shape in the bottom right of the
plots in Figure3. Given a Tail Size (  ) value, denoting what bottom percentile of tour songs
are to be considered a part of the tail, a Tail Val uecan be calculated as the ratio of a tour’s

        <p>Covers - For each song played on the tour we have information denoting which are cover songs
(with respect to the artist), from which the shelf songs that are cover songs, and the tail songs
that are cover songs, can be determined. From this, the set of shelf songs minus those that are
covers can be determined and a Shelf Minus Covers Ratio Value
calculated. Similarity,
the set of tail songs minus those that are covers can be determined and a Tail Minus Covers</p>
        <p>These calculated notions of Shelf, Tail, 100%’ers, Uniques and Covers can be highlighted
visually within our tour plots, as shown for the tours introduced earlier of Bruce Springsteen
(and the E-Street Band’s) 2023 tour in Figure4a, and Coldplay’s Music of the Spheres 2023
Tour in Figure4b. In these plots, the shelf lower edge is denoted via a dotted green line and
the 100%s’ers are those songs that sit on the solid green line. The tail upper edge is denoted via
a dotted orange line and the uniques are those songs that sit on the solid orange line. Cover
songs are denoted by filled red data points, and the shelf and tail covers can be identified as
those filled data points above the shelf’s lower edge and below the tail’s upper edge respectively.
Here, and within subsequent analysis , and</p>
        <p>parameters of 10% are utilised. However, these
parameters can be altered to any desired numbers. For experimentation exploring sensitively
analysis and impacts of these parameters see AppendiAx.</p>
        <p>Such analysis can be utilised to explore and compare diferent tours from the same artist and
to compare tours of diferent artists. For example, regarding other Bruce Springsteen tours, the
plot for the Wrecking ball tour is shown in Figu4rceand the plot for the Bruce Springsteen on
Broadway tour shown in Figur4ed. These plots highlight how, as in The Wrecking ball tour’s
case, a tour can have quite a small and sharp shelf, or, as in the Bruce Springsteen on Broadway
tour, a tour can alternatively be predominantly made up of a shelf. The tour for Taylor Swift’s
Speak Now World Tour is shown in Figur4ee, highlighting a tour which has a large long tail
that is made up of many uniques that are cover songs. The tour for Pink Floyd’s The Wall tour

        <title>3.4. Artist Career of Tours Analysis</title>
        <p>For a single tour, its Shelf Val ueand Tail Valu e can be calculated. With the calculation of a
pair of such values for every tour of an artist’s career, their whole career can be visualised, in
chronological order, in a bar plot. Such a visualisation, for every tour for Bruce Springsteen is
shown in Figure5a. Here, for each tour, tail values are shown as negative blue bars and each
tour’s corresponding shelf values are shown as green bars.</p>
        <p>Additionally, for each tour, its 100%’ers Valueand Uniques Value can be calculated.
These pair of values represent values equal to or less than the to ura’nsd  values. Therefore,
an artist’s whole career can be visualised in a bar plot where the amount of each tour’s tail
that is made up of uniques, and the amount of each tour’s shelf that is made up of 100%’ers is
highlighted. For Bruce Springsteen, every tour with this information is shown in Fig5ubr.e</p>
        <p>Moreover, for each tour the amount of its shelf that is made up of covers, and the amount
of its tail that is made up of covers can be calculated. Then, an artist’s whole career can be
visualised with the amount of each tour’s tail that is made up of covers, and the amount of
each tour’s shelf that is made up of covers highlighted. Every tour for Bruce Springsteen with
this information is shown in Figur5ec. Alternatively, we could visualise the impact of cover
songs on each tour’s shelf and tail through calculating each tour’s Shelf Minus Covers Value
 and Tail Minus Covers Valu e . Then, an artist’s whole career can be visualised,
highlighting how shelves or tails that are made up of a substantial amount of cover songs will
become smaller. Every tour for Bruce Springsteen with this information is shown in Fi5gdu.re</p>
        <p>Such analysis can be utilised to explore and compare the careers of diferent artists. For
example, Figure6a shows the career of Iron Maiden, and Figur6eb shows the career of Slipknot,
each showing Shelf and Tail values and how much of them are taken up by 100%s and Uniques.
These plots highlight how these artists have a clear leaning towards playing more conformity
and greatest hits like sets, and highlight how over their career this has only become more
pronounced. The career of Taylor swift, showing each tour’s Shelf and Tail values and how
much of them are taken up by covers, is shown in Figur6ec. Here, we observe how after her
ifrst tour, a similar size of shelves and tails is observed. However, whereas the Speak Now
World Tour’s tail is made up almost entirely of cover songs, we observe the inverse for the
tail of the most recent Eras tour. The range of diferent shelf and tail values for the tour’s of
Pink Floyd are shown in Figur6ed. From this plot we observe stark diferences between early
tours which have little or no shelves, and later tours, that coincide with their commercial peak,

creating a scatter plot of these results, as shown in Figu8r.e In this plot, we see how some
artists, that play a lot of covers within their tail, move further away from the top right of
the plot, highlighting the importance, for some artists, of playing cover songs as part of their
attainment of variety1.5</p>
        <p>From Figures7 and 8’s data, additional analysis can compute overall averages for each
generalized genre. Calculated genre averages, for Tail and Shelf values are shown in Fi9gau.re
The plot highlights how genres, such as Electronic and Dance, and Pop, on average exhibit
less variety that other genres, such as Folk, Alternative, and Punk. Calculated genre averages,
when shelf and tail cover songs are not considered are shown in Figu9br.e Here, we observe
the impacts removing covers has on the genre averages, and how the impacts are greater for
some genres, such Rock and Alternative, than others, such as Punk.</p>

        <p>To examine the robustness of our notion of variety for comparing diferent artists, despite their
varying characteristics, such as the number of tours, the length of performances, and activity
during diferent time periods, we conducted a correlation analysis between o ū rVariety

with definitions of each property. The Correlation values are the correlation levels found
between each of the seven properties and our ̄ measure. Here, correlation is calculated with

these properties see AppendixC, which also contains visualisation scatter plots of each
property against our ̄ measure. Table3 highlights how our measure has only very weak correlation
to these properties1,6 suggesting our measure is robust for analysis between artists, and will
not be unduly bias by, for example, diferent artists having more tours or longer shows.

      <title>4. Conclusions</title>
      <p>In this paper, we explored data acquisition and processing of musical artists’ touring histories,
and proposed an approach to explore set-list variety, at tour level, artist career level, and for
comparisons between artists. Our approach proposed the notions of a shelf and a tail, to aid
explorations of, and to quantify, variety at tour level and artist level. Furthermore, the
approach explores the impact of cover songs on these notions of variety, and explores variety
comparisons between diferent musical genres. The analysis of variety highlighted the
diversity among artists, in terms of a prevalence to lean towards playing more conformative or more
diverse shows. Additional correlation analysis explored the robustness of the proposed notion
of variety, with respect to difering artist properties, such as the number of tours or the average
lengths of shows.</p>
      <p>From our data processing, some data quality issues were uncovered, such as incomplete or
empty data, for which such instances can be flagged, and filtering thresholds utilised.
Generally, we found more setlist.fm data issues for older tours and shows, and for less popular
artists. Additionally, setlist.fm provides set-list data without details on other potential set-list
semantics, such as variations in how a song is performed or the inclusion of special elements
like artist monologues or other forms of communication during a show. Therefore,future work
will explore integrating additional data sources, such as artist fan community databases, to
enrich our dataset and model, ofering potential for incremental improvements. Additionally,
future work will investigate incorporating our analysis into live music recommender systems,
which suggest items based on user preferences4[]. Given that factors such as variety and
diversity have become increasingly important in this field 1[8], our analysis may provide valuable
insights.

      <title>A. Exploration of Shelf and Tail Parameter Values</title>
      <p>To aid selection of pertinent and   parameters, and to aid understanding our of dataset,
sensitively analysis experimentation was performed exploring the average percentage of tour
songs that are contained within diferent combined shelf and tail size parameter values. The
impact of experimentation with diferent sized shelf and tail values is shown in Figu1r1e. The
x-axis denotes diferent combined sizes of shelf and tail values (so 20 represents where the shelf
and tail values are both 10) and the y-axis denotes the overall average percentage of songs that
are contained within the combined shelf and tail.</p>
      <p>Figure11 highlights how, due to the general trend observed for tours to map out an s shaped
sigmoidal like function, there is a pattern that the percentage of songs contained within the
shelf and tail is greater than the percentile values denoting the shelf and tail size. From example,
a shelf and tail percentile size both of 10% (20% combined value) results in over 50% on average
of tours’ songs being contained within this 20% percentile space. Moreover, these values denote
a point in the plot where the decrease of the gradient of the line is levelling of, suggesting their
suitability as shelf and tail percentile sizes.</p>
      <p>Further analysis could explore additional experimentation such as, breaking the results down
to see the separate contributions of the shelf and tail to the total, using unequal shelf and tail
size values, and exploring diferences within the results when the data is subsetted for features
such as genre.</p>
    </sec>
    <sec id="sec-6">
      <title>B. Ordinal Clustering Analysis</title>
      <p>From calculations of a pair of̄ and  ̄ values for every artist, the whole set of artists can be
visualised within a single scatter plot, as shown in Figure 7, and from calculations of shelves and
tails not including cover songs, the set of artists can be visualised within a single scatter plot, as
shown in Figure 8. Further analysis of the data in Figures 7 and 8 can cluster artists into ordinal
groups by dividing the 2-dimensional plot space. Variety can be viewed as a combination of
levels of shelves and tails, with the plot space divided accordingly, as shown in Fig1u2ar,ehere,
for average shelf and tail values for each artist. In this plot, the dotted red lines divide the space
into 8 levels of variety, representing 8 ordinal clusters. Each artist belongs to only one cluster,
as shown by the data point colours in Figur1e2a. The membership constraints of each of the 8
clusters can be defined in terms of mean shelf ( )̄ and mean tail ( ̄) value ranges, and assigned
semantic ordinal names such as:

Combined Shelf and Tail Values
1. Very High Variety: Where the diference between the mean tail and mean shelf value
is greater than or equal to 75.
2. High Variety: Where the diference between the mean tail and mean shelf value is
greater than or equal to 50 and less than 75.
3. Moderate Variety: Where the diference between the mean tail and mean shelf value
is greater than or equal to 25 and less than 50.
4. Low Variety: Where the diference between the mean tail and mean shelf value is
greater than or equal to 0 and less than 25.
5. Low Uniformity: Where the diference between the mean tail and mean shelf value is
greater than or equal to -25 and less than 0.
6. Moderate Uniformity: Where the diference between the mean tail and mean shelf
value is greater than or equal to -50 and less than -25.
7. High Uniformity: Where the diference between the mean tail and mean shelf value is
greater than or equal to -75 and less than -50.
8. Very High Uniformity: Where the diference between the mean tail and mean shelf
value is less than -75.</p>
      <p>Similar analysis can be conducted for data calculations of shelves and tails not including
any songs that are cover songs, as shown in Figur1e2b. Here, we observe that when covers
are excluded, some artists shift in the plot to the extent that they belong to a diferent cluster,
invariably one with less variety. Within such cluster analysis, the % of artists in each cluster can
be computed. The breakdown of each cluster artist %, for both data including cover songs, and
data not considering cover songs, is shown in Tabl4e. The Table highlights how when cover
songs are not considered, cluster memberships exhibit a general trend for the distribution to
move from variety to uniformity.
The explored properties and results are shown in Ta5b,laend visualisation scatter plots of each
property against ou r ̄ measure are shown in Figure1s3 – 16. Next, each property is outlined
and discussed.</p>
      <p>Number of Tours: Our dataset includes artists with varying numbers of tours. Figu1r3ea
compares each artist’s tour count with thei r̄, showing no strong relationship between the
variables. The Pearson Correlation CoefÏcient value for these two variables is -0.1786.
Total Number of Shows: For the artists in our dataset, the overall number of shows varies.
Comparisons between artists’ total show count and thei r̄is shown in Figure13b. Here, the
plot highlights there is no strong relationship between these variables; the Pearson Correlation</p>
      <sec id="sec-6-1">
        <title>CoefÏcient value for these two variables is -0.0725.</title>
        <p>Length of Tours: Within our dataset, the number of shows within our artists’ tours difers.
Comparisons between each artist’s average tour show count and th eir̄is shown in Figure14a,
and the correlation value between these variables is 0.0908. The outlier in the plot is due to the
fact Bob Dylan’s ”Never Ending Tour” is ofÏcially billed as a single continuous tour spanning
from 1988 to present day and contains around 4000 shows. A plot with Bob Dylan excluded to
aid readability is shown in Figur1e4b.</p>
        <p>
          Average Show Length: For our set of artists, their average show length, in terms of the
number of songs in the set-lists, varies. Comparisons of each artist’s average show Length and their
 ̄ is shown in Figure15a, and the correlation value between these variables is 0.0952.
H-Index: The H-index is a scientific output metric that quantifies both the productivity and
citation impact of a researcher’s publications, where a scholar has an index of h if h of their
papers have been cited at least h times each 1[
          <xref ref-type="bibr" rid="ref1">4</xref>
          ]. We could consider this notion within the
setlist domain as a measure for an artist (instead of a researcher) and songs (instead of papers),
where an artist has a h-index of h if they have played h songs at least h times each. To calculate
this for each artist, the set of tours for an artist is combined and overall songs counts calculated
from which the H-Index can then be derived from. The plot comparing artists’ H-Index against
 ̄ is shown in Figure15b, and the correlation value between these variables is 0.0630.
Artist Start Dates and Amount of Active Years (Groups Only): For the groups within our
artist dataset, information pertaining to the groups formation start date and, if applicable,
disbandment date (denoted as present day for still going groups) is retrieved from MusicBrainz.
Comparisons of each group’s start date and their̄ is shown in Figure16a, and the correlation
value between these variables is 0.0933. From this timeline data, the length of time each group
were/have been active for can be calculated (with groups that are still active measured up to
present day). Comparisons of each group’s Years Active and the i r̄is shown in Figure16b,
and the correlation value between these variables is -0.0952.
        </p>
        <p>The set of correlation values for these properties again̄sits shown in Table5. Considering
correlation strength classified as, Very Weak Correlation||: &lt; 0.2 , Weak Correlation:0.2 ≤
|| &lt; 0.4 , Moderate Correlation0:.4 ≤ || &lt; 0.6 , Strong Correlation0:.6 ≤ || &lt; 0.8 , Very
Strong Correlation|:| ≥ 0.8 [12], Table5 highlights how ou r ̄ variety measure has only very
weak correlation to all these properties. This suggests the measure is robust across the varying
properties for our artists, and that comparisons between artists are not unduly impacted by
these variations.
