    A B S T R A C T Musical imagery is the experience of imagining music in the minds

    ear. A study was conducted to explore the prevalence and nature of musical

    imagery for music students in everyday life, using experience-sampling methods

    (ESM). As a group, music students reported that imagining music was a very

    frequent form of musical experience. Participants reported individual variation

    in their imagery experience but also common differences between the strength of

    imagery for different musical dimensions. For instance, melody and lyrics were

    rated as being more vivid components of the image than timbre and expression.

    Another clear pattern was the influence of hearing music on musical imagination,

    one indicator being that 58 percent of sampled episodes described having heard

    or performed the music recently as a possible reason for currently imagining it.

    K E Y W O R D S: everyday music, experience-sampling methods, mental imagery

    Introduction

    Whether musicians are composing, performing, analysing, reading or

    listening to music, the ability to audiate (Walters, 1989) and intentionally

    imagine sound is important. Yet comparatively little is known about this

    silent dimension of musical experience, the musical image (Bailes, 2002;

    Gody and Jrgensen, 2001). Musical imagery can be defined as the experi-

    ence of imagining musical sound in the absence of directly corresponding

    sound stimulation from the physical environment. While musicians arepresumed to experience musical imagery in their music-specific activities,

    they are similarly presumed to experience the more everyday occurrence of

    having an involuntary tune on the brain. The idea that musicians are

    particularly prone to imagining music reflects a belief that the more an

    individual is exposed to particular music in everyday life, the more they

    might imagine that music. This connection between music heard and music

    imagined might explain the common experience of having a recentlyperceived musical fragment on the brain.

    Little empirical research to date has explored the prevalence of musical

    imagery in everyday life, though the function and properties of musical

    imagery have begun to form the focus of experimental research conducted in

    laboratory settings. For example, Halpern (1988) demonstrated that partic-

    ipants could intentionally imagine songs from an early lyric to a later lyric

    analogously to the time needed to hear the corresponding portion of music.

    Technological advances in neuroscience have allowed for studies of the

    neurological similarities and dissimilarities between hearing and imagining

    music (Zatorre and Halpern, 1993; Zatorre et al., 1996; Janata, 2001). Other

    research has looked at the qualia or characteristic features of the mental

    sound experience, ranging from timbre (Crowder, 1989; Pitt and Crowder,1992) to expressive timing (Repp, 2001). Brodsky et al. (2003) examined the

    factors that interfere with the accurate imagining of a musical score.

    Orchestral musicians were required to match sounded melodies to their

    mental image of the well-known melody hidden within a score. Results

    suggest that the expert musicians participating in the research varied greatly

    in their ability to inwardly hear notated music.

    In order to measure the prevalence of musical imagery for musicians

    beyond the laboratory setting, be that intentional or unintentional imaging,

    it is important to sample experience as it occurs naturally. Accordingly, a

    study adapting experience-sampling methods (ESM) was devised by the

    author to allow participants to record details about their musical imagery,

    current activity, mood and musical environment when contacted by theresearcher at random times throughout the day. The methods in this research

    and a discussion of the use of ESM to study musical imagery are described in

    Bailes (2006). The work builds on a study by Sloboda et al. (2001), who made

    use of ESM to explore musical experience in the everyday life of eight partic-

    ipants. North et al. (2004) also used sampling methods, though on a larger

    scale (346 respondents), to address similar issues. Neither study focused on

    imagining music. Rather, both studies gathered information regarding the

    relationship of respondents to their musical environment, and concluded

    that hearing music was frequent throughout the day (44% of episodes for

    Sloboda et al., 39% for North et al.), and that music was used by participants

    to serve different purposes and suit different contexts.

    This article follows on from the methodological presentation of the project

    in Bailes (2006) to report a summary of the main findings. The project

    investigates musical imagery experience in the daily lives of music students.

    The data are too extensive to report in full in this article. Rather, the purpose

    is to describe early results that raise questions of relevance to an under-

    standing of musical imagery. By monitoring the occurrence of the everyday

    tune on the brain, we may begin to develop a clearer understanding of its

    role in daily life.

    MethodIn the experience-sampling method, participants are cued to provide specific

    information at random times throughout the day, during a period of several

    days. The method allows respondents to provide an immediate response

    rather than a retrospective report, and does not divorce participants from

    their current locations and activities.

    PARTICIPANTS

    Participants were 11 undergraduate and postgraduate music students at the

    University of Sheffield, UK (five men and six women).

    MATERIALSParticipants were called on their mobile telephone, which they had set to the

    silent vibrate mode. As soon as possible after receiving a call, they filled in an

    experience-sampling form (ESF), designed to be completed within a few

    minutes (see Appendix). In the eventuality that participants were unable to

    fill out the form immediately upon hearing the signal, there was space to note

    separately the time of the signal and the time of form completion. The ESF

    comprised three parts. The first part asked for general information as to the

    time of signal, location, activity and the presence of others. The second part

    was for completion when participants were actually hearing music. The final

    part was for completion when participants were imagining music. Questions

    included what music was being imagined, vividness ratings for different

    dimensions of the image, self-rating of mood and open questions as topossible reasons for imagining that particular music. Participants were each

    provided with 42 ESFs (6 forms 7 days).

    PROCEDURE

    Participants received random calls between 10:00 am and 10:00 pm each

    day, for seven consecutive days. The researcher called the participants one

    after another in immediate succession, once within a two-hour block, with a

    minimum of 20 minutes and a maximum of three hours and 45 minutes

    between each call. At the end of the study, participants were interviewed

    about their experiences.

    Analysis

    Analyses of general trends in imaging, hearing and no music episodes were

    based on all 417 completed ESFs. As respondents were asked to provide data

    in relation to the time of signal rather than the time of completion, more

    detailed analyses of episodes were based on the 350 forms that had been

    completed within 30 minutes of the signal (calculated from the researchers

    recorded time of call in relation to the participants indicated time of ESF

    completion). This was to avoid overly retrospective data. Results are primarilydescriptions of summary data across all episodes, while ANOVA and chi-

    square measures are based on individual participant response, and qualita-

    tive analyses refer to open questions on the ESF and post-study interview

    feedback.

    Results

    There was a 90 percent response rate representing a total of 417 completed

    ESFs, called episodes. Because experience was sampled randomly through-

    out the week, the time participants spent in each musical state of imagining

    or hearing could be inferred. Results are shown in Figure 1, where the

    category both applies to seven out of 11 respondents who indicated thatthey had simultaneously heard one piece of music while imagining another.

    There is great individual variation within this global measure of the

    prevalence of imagery. The participant who experienced the least imagery did

    so for 12 percent of the time, while one participant reported imagining music

    as much as 53 percent of the sampled time.

    As Figure 2 illustrates, there was a tendency for the percentage of actually

    heard music to increase throughout the day (with only 35% of episodes

    involving heard music during the earliest period from 10:00 am to 12:00 pm,

    and 59% during the latest period of 8:00 pm to 10:00 pm). The number of

    reported imagery episodes remained constant, before dropping to almost half

    that number during the final testing period (8:00 pm to 10:00 pm).1 There

    was a decrease in the number of no music episodes reported throughout the

    day, though these slightly increased in number during the final testing period

    (from 12% at 6:00 pm to 8:00 pm, to 21% from 8:00 pm to 10:00 pm).

    The main activity of respondents at the time of the signal was measured.

    This was to look for any apparent relationship between activity-type and

    musical thought. Responses were subsequently grouped into categories to

    include activities as diverse as talking, watching television, listening to music,

    rehearsing, buying groceries, sitting, teaching, waiting, eating dinner and

    surfing the internet.

    Figure 3 shows that imagery episodes were most frequent during inter-action with others, with working the second most frequent activity. It is

    worth noting that while watching television often involved heard music,

    respondents were less likely to be imagining music than experiencing no

    music at this time. Activities categorized as time filler (for instance, waiting,

    lying in bed) and states of being (for instance, getting up, sitting) were twice

    as likely to be accompanied by imagery as by heard music. Travelling is

    associated with more imagery than hearing music episodes.

    When no music is physically present, the company of other people might

    have a bearing on whether an individual is prone to imagine music or is

    music-free. A chi-square test for the frequency with which heard, imagery

    and no music episodes coincided with the presence of others (see Figure 4)

    shows a significantly non-random distribution (2 = 6.29; d.f. = 2;p < .05). Itis noteworthy that the imagery data resemble patterns for heard music more

    than those for music-free episodes, occurring more in the presence of others

    than alone.

    Fifteen percent of all completed ESFs were filled out more than half an

    hour later than the time of signal: all these data were discounted for the

    purposes of the following more detailed analyses. This left a collection of 350

    responses (76% of all possible returns). The following analyses were based

    solely on these 350 episodes. Findings are discussed thematically under

    characteristics of musical imagery and when and why it occurs.

    CHARACTERISTICS OF EVERYDAY MUSICAL IMAGERY

    In relation to their musical imagery at the time they were contacted,

    participants were asked How aware of the imagined music were you? and

    How much were you concentrating on the music? On the whole, respon-

    dents were quite aware of the music they imagined (rating above average on

    a scale between not at all and very much so), though not concentratingparticularly on it (mostly average rating and under). Contrary to the common

    belief that music on the brain is an irritant, the music students in this study

    mostly stated that they wouldnt wish to be imagining different music, or

    even no music at all.

    For each imagery episode, vividness ratings were recorded for the musical

    dimensions of melody, timbre, harmony, expression, dynamics, texture, lyrics

    and physical memory of playing (where appropriate). A mean value for each

    dimension per participant was calculated, and these data were analysed with

    a one-way ANOVA. Mean ratings between dimensions were significantly dif-

    ferent (F7 49 = 5.45; M= 4.16; SD = 0.9;p < .0001) and Figure 5 illustrates

    the resultant hierarchy of vivid features (1 = absent, 7 = very vivid), averaged

    across all participants.

    Standard deviation bars have been included in Figure 5 to give an idea of

    the amount of agreement between participants on the vividness of each

    dimension. Melody and lyrics are rated as being the most vivid dimensions of

    musical imagery. Timbre is less vivid than melody for these respondents. For

    those times when the respondent reported having performed the music they

    were imagining, the degree to which they imagined a physical memory of

    playing was measured. The mean response is 3.7 on a scale from 1 (absent)

    to 7 (very sharp), though there was high variability. Most participants were

    agreed that expression was not particularly vivid in their imagery. Dynamics

    and harmony were rated as being the least vivid components of a musical

    image.

    The ESF did not include a separate category to measure the vividness ofimagery and perception for rhythm, though one participant was keen to

    point out that his imagery was most often centred on this. No respondents

    reported an association between the rhythms they perceived or rhythmic

    importance and the music they imaged, though this does not rule out an

    unconscious association. Also note that this analysis does not take the mus-

    ical features of the particular music being imaged into account, and these

    can be expected to have an important bearing on the vividness of different

    dimensions. For example, a person imagining a piece of atonal music would

    be unlikely to imagine a veridical harmonic scheme, and a person imagining

    meditation music without a clear beat would be unlikely to report a veridical

    rhythmic component.

    An open question asked respondents to outline how complete anexperience their imagery was. The majority of episodes describe the image as

    a repeated fragment rather than a full mental run-through. Very often the

    repeated segment was the chorus of a song. Varying levels of clarity in the

    image were sometimes described in this section of the ESF, ranging from

    quite hazy to the imagining of baroque instrument timbre. In a couple of

    episodes, a spatial location in the head is associated with the image: music is

    heard at the back of the mind, or salient elements appear at the front. Multi-

    modal aspects of musical imagery are described, such as imagining a score,

    imagining the video of a pop song, imagining the physical aspect of getting a

    piece right, dancing, and visualizing a specific performer.

    The ESF did not take into account the possibility of imagining and hearing

    different music simultaneously. Post-experiment interviews checked that allrespondents who did experience this managed to note it down in some form.

    When asked what this experience was like, respondents spoke of concen-

    tration being shared between both heard and imagined music, and of

    multiple layers of awareness. For instance, one participant reported hearing

    a particular piece of music passively, but as it was unfamiliar to him he had

    continued to imagine some familiar music that he had previously heard.

    The possible relationship of mood to imagery was investigated.2 Table 1

    presents the overall frequency of mood ratings for all imagery episodes. The

    most frequent ratings per mood-pair are highlighted.

    Mood-pairs in Table 1 are grouped according to the three primary factors

    borrowed from a principal components factor analysis of mood change,

    before and after listening to music, from the study by Sloboda et al. (2001).

    The factors named by these authors are positivity, present-mindedness and

    arousal. Data from the current study do not examine mood change and can

    only be viewed as descriptive patterns of mood at the time of imagery

    episodes. Nevertheless, respondents reported above average positivity (happy

    and relaxed), and arousal (alert and energetic) based on their subjective

    interpretation of the response scales. Present-mindedness as represented

    by the scales of interested/bored, involved/detached, and connected/lonely,

    received generally neutral ratings.

    The ESF did not ask participants to distinguish between voluntary andinvoluntary imaging of music. Consequently, we cannot be sure to what

    extent they were experiencing an unintentional tune on the brain, or

    intentionally rehearsing or creating music in the mind. Some of the imagined

    music was the students own compositions. However, the proportion was

    relatively small (eight out of 123 episodes) stemming from the only four

    respondents actively composing at the time of the study. Music imagined

    covered a large variety of genres. For imagery episodes, a total of 89 different

    pieces of music were named, while 18 episodes were unnamed music. For

    heard music episodes, 81 different pieces were named, and 103 episodes were

    unnamed. A generalized chi-square shows this distribution to be significant

    (2 = 41.19; d.f. = 1; p < .0005). On the whole, respondents were able to

    name the music they were imagining: this declarative knowledge suggests afairly high level of familiarity with the perceptual source of their imagery.

    It seems probable that musicians recently hearing or performing music

    would subsequently imagine it. Two questions on the ESF addressed this

    question directly. In response to the first question, Had you actually heard

    this music since the last time you were contacted? 43 percent replied yes

    and 54 percent replied no (3% answers missing). This question only related

    back in time to the last call received and it is possible that hearing music less

    recently, for example within the last week, might also have an importantinfluence on music imagined. This possibility is accounted for by a second

    question, If possible, please explain why you might have been imagining that

    particular music, allowing for a more open-ended explanation for the

    possible occurrence of particular music. Results in Table 2 have been grouped

    according to the category of reason participants offered for imagining

    particular music, and relate to the 107 completed responses for this question.

    Categories of response include the following: visual trigger, music to be

    performed (e.g. preparing it for music department opera), analytical

    listening (e.g. working on it at the time), reaction to experiment (e.g. talking

    about experiment), person association (e.g. being asked about improvisation

    and thinking about someone in particular improvising), heard it, talked

    about it (e.g. talking about Pop Idol before I left home), stickiness orautomatic (e.g. tune often in my head), similar to something heard (e.g.

    dont know it, but similar to piece Im performing), triggered by the name of

    the music, liking the music and nostalgia (e.g. cousin sang it as a child).

    Discussion

    Does imagining music occur as a result of recently hearing music? This study

    has provided data consistent with links between heard and imagined music.

    For instance, 43 percent of episodes stated that music had been imagined

    since the last time the respondent was contacted, while in response to an

    open question, 58 percent of episodes offered having heard or performed the

    music recently as a possible reason for imagining it. The dependence ofimagery on perception is supported by the significant majority of imagery

    episodes as compared with heard music episodes that could be named by res-

    pondents; this implies familiarity and repeated perception prior to imagining.

    Moreover, attending to particular musical dimensions in listening might have

    affected the characteristics of the consequent image for the music students in

    this study.

    Vividness ratings show that different musical dimensions were reportedly

    imaged to a different extent, with melody and song lyrics the most vivid, and

    timbre, harmony and expression the least vivid. It is notable that the most

    prominent features of the imagery were pitch or word based, demonstrating

    the appropriateness of the expression tune on the brain as opposed to music

    on the brain. Why are timbre or texture less vivid dimensions of the image?One of the ways in which they differ from melody and lyrics is that while

    melody can be sung, the physical limitations of the human voice make it

    impossible to reproduce non-vocal timbres and textures. It may be more

    difficult to image a very well-known but physically impossible timbre than to

    image the timbre of the voice (see also Halpern et al., 2002). As for expres-

    sion and dynamics, Snyder (2000) writes that expressive nuance tends to by-

    pass long-term memory, as it cannot be categorized as easily as the invariant

    structural elements of music such as pitch, though this would not preclude

    the generation of expressive nuance at the time of imaging.

    What is the role of the tune on the brain? An overview of the most

    common activity-type during imagery episodes revealed a surprising pattern,

    namely that imagery was most frequent during interaction with others andwork. Intuitively, the active participatory nature of reacting to others and

    working might seem to demand a level of concentration likely to suppress

    extraneous musical thought. There are known to be optimal levels of arousal

    and attention in order to perform tasks of different complexity. Hearing music

    is known to have a physiological impact on arousal levels (for a reference on

    mood and arousal see Thayer, 1989). It could be speculated that in the

    absence of actual music, the generation of imagined music operates to either

    self-regulate or to match levels of arousal. This is a potentially important area

    for future investigation.

    There are reasons to argue that rhythm is a central component to musical

    imagery. Future research might explore a relationship between conscious and

    unconscious rhythmic triggers of the image, and associations between

    arousal level and the rhythmic component of musical imagery. Additional

    dimensions of musical imagery mentioned by respondents in the study

    include visual, spatial and kinaesthetic properties. It is probable that the

    multi-dimensional nature of the musical image differs with respect to a

    variety of factors. For example, important areas to explore are the impact on

    imagery experience of awareness and concentration when listening to music,

    personal musical taste and musical genre.

    In conclusion, this study describes the prevalence of musical imageryexperience for music students for the first time. In the process, it has begun to

    reveal a multitude of important issues for future research, ranging from

    characteristic sound features of the image, to the conditions of its

    occurrence, and ultimately its function in everyday life.

    1. A chi-square test of the distribution of heard, imagery and no music episodes

    across the two final testing periods of 68 pm and 810 pm did not reveal a

    statistically significant pattern (2 = 4.37; d.f. = 2;p < 0.2)

    2. Due to space limitations on the ESF, no comparative data were gathered regarding

    mood during perception and no music episodes. Please refer to Sloboda et al.

    (2001) for comparable mood ratings as a function of music listening.
