Musical
Chairs: From Spectator to Stage
1. What
is Musical Chairs?
Musical Chairs is a touch-based interactive music exploration
application (“app”), designed for tablet devices (iPad and iPad mini) and is
currently available for the iOS platform. The application enables users to explore
multi-channel high-definition videos of recorded musical performances, allowing
users to zoom and pan through the performances with standard touch gestures,
with the volume of each channel dynamically mixed based on the point of focus
in the video stream. In doing so, the
audio adapts to the visual focus, bringing to prominence channels whose sources
are on screen or nearly on screen, while downplaying channels whose sources are
far from the current focus of attention.
This allows users
to isolate specific audio and visual aspects of a musical performance and creates the
illusion of the user physically moving through the performance in real-time,
somewhat akin to a “Google Street View” for musical performances, using
seamless video and audio instead of connected still photos with no sound. Enabling this type of listening for musical ensembles may provide
users a way of engaging in music listening in a participatory and active way,
and therefore could result in more sustained interest in
group and individual musical performances.
2. How it
Works
For example, consider the sequence of images in Figures 1 and 2 in
Appendix A of this document, depicting a user using Musical Chairs to explore
the performance of a quintet. The
performance begins with Figure 1(a), with the full ensemble being shown. With all performers on screen, all performers
can be heard equally, with their audio mixed appropriately for stereo
output. (The first and second performers
are more prominent in the left stereo channel, while the fourth and fifth are
more prominent in the right stereo channel.)
In Figure 1(b) the user uses a pinch-to-zoom gesture to focus on the
second performer. In doing so, the
second performer’s volume is increased while the other performers are decreased
accordingly. In Figure 1(c) this operation
is completed, and the second performer’s contribution now dominates what the
user hears; the first performer can be faintly heard in the left stereo channel
still, while the remaining performers can be faintly heard in the right stereo
channel with volume decreasing with distance to the second performer. To hear both the first and second performers,
the user begins a swipe-to-pan action in Figure 1(d) and completes this in
Figure 1(e). With both performers on
screen, their contributions can be heard equally well, although again mixed
into left and right stereo channels appropriately. The other performers, now even farther away
from the focus are even quieter than before.
To focus on the third performer, the user zooms out and then begins a
pinch-to-zoom action in Figure 1(f) and completes this in Figure 2(a). As the zoom out is performed, all of the
performers are brought back into focus and can be heard again; when the zoom to
the third performer is carried out, his contribution dominates what the user
hears, while the other performers can be heard faintly in the background of the
left and right stereo channels. In
Figure 2(b) the user has zoomed out and then in again on the fifth performer,
causing his contribution to dominate.
Through Figures 2(c), 2(d), and 2(e), the user pans through the entire
ensemble from right to left. Doing so
creates an interesting effect, with performers moving from the left channel, to
dominating both channels, to the right channel, and then fading off to the
right as the focus of the performance shifts. The performance ends in Figure
2(f) with the user zooming out to hear the entire ensemble as in Figure
1(a). Through a variety of simple touch
gestures, the user has effective moved through the performance, focusing their
attention on different performers and aspects of the music. As such, Musical Chairs supports
interactive musical exploration in ways that have previously not been possible.
3. Why?
The Need for Engaged and Interactive Listening
The creation
of the Musical Chairs application stems from an interest in music education
technology, and specifically, engaged listening of recorded musical
performances. The literature in music education emphasizes the necessity for
innovative ways of providing students with experiences that reflect their own
culture. Students, now widely described as digital natives, have various ways
of listening and experiencing music inside and outside of the classroom. This
includes using devices such as iPods and iPads to access and download, or view
and listen to, any type of music they choose. Buckingham1 describes
how students need to critically engage in digital literacies, including
interactive listening technologies such as iPods and iPads. This reinforces the
purpose of Musical Chairs, which “addresses a range of musical and
technological skills that widen the opportunity for students in music beyond
music education’s traditional approaches”. The speed at which music education
technology has evolved is astounding. New music technologies are being
introduced quickly and effectively to learners of all ages. While educators are
constantly aware of musical styles as a form of student’s personal identity, it
has become more urgent to address their ways of consumption as well. As Finney2
explains, teachers and students use different musical codes, and it may be that
some are at opposite ends of a “musical and linguistic chasm with few holding
the key to unlock each other’s code” (p. 18). Finney explains that if we are
unresponsive to our students’ pedagogical needs, their ways of knowing,
understanding, and identifying with music, we can potentially have a negative
effect on their personal autonomy and creative capabilities in music.
Similarly, Ruthmann & Dillon3 agree
and add that we must allow for students’ agency through understanding how
students use music and experience technology. By doing this, we can begin to
understand students’ own culture and model a ‘relational pedagogy’ in the
classroom.
Creating this application with a focus on engaged listening,
necessitates an investigation into the quality of interaction students have
with technology. Researchers such as Green4,5
describe the extremes within types of listening that students engage in; from
purposive listening, to distracted listening. The difference is that with
purposive listening, students are actively engaging in the music or instruments
being played, where distracted listening is often music heard in the background
and not the focus of the student. In addition, it is possible that distracted
listening may occur even when purposive listening is the goal.
Beyond music education and research, there are a number of broad and
general applications to music exploration and interaction, as the technology
enables everyone to work or play with music in ways that were previously not
possible. The ability to stream and/or
download performances also creates numerous social music applications, with
users able to share their recorded performances with one another for a variety
of purposes. For example, an ensemble or
band can record one of their performances and view the recording later, making
personal notes for improvement. The
ensemble or band could also share their performance with partners or labels as
a form of demo for business or audition purposes. The ensemble or band can also share their
performances with an audience or fans, just to share their music with
others.

Presentations and the Research
We are currently conducting formal research projects using this
technology.
The
Engaged Listening Project 1 (ELP1) – Research is currently being conducting how people
listen to music. More specifically, when listening to a pre-recorded live
performance, we are analyzing what specific aspects of a performance attract
listeners. (What do they listen to, at what point during the piece, for how
long, etc.) Using the ‘app’ Musical Chairs: From Spectator to Stage enables
this research by having participants listen and watch performances, and
recording their activities collected as data. The data is analyzed for emerging
patterns.
The
Engaged Listening Project 2 (ELP2) – In this study, students enrolled in Grade 9 music
classes are asked to use the ‘app’ to assist them in learning a new piece of
music. The recording is made from Grade 12 music students in the same school.
This case study investigates whether or not the ‘app’ is useful for students
learning to play new pieces, whether this influences their future choices to
enroll in music classes. The results will be informed by semi-structured
interviews with the participating students and teacher.
The
Engaged Listening Project 3 (ELP3) – This research is analyzing its use and potential as a data gathering tool for qualitative researchers. We are
investigating ways of tracking audio/visual data which will
enable qualitative researchers to capture all participants’ anecdotal ‘field
notes’ and conversations in an efficient and accurate manner.
The app has been
presented many times within the Western University Community, such as in-class
lectures, invited lectures in undergraduate and graduate classes, and many
other presentations. The list below
