Abstract: | This article introduces a new method of data analysis that represents the playing of written music as a graph. The method,
inspired by Miklaszewski, charts low-level note timings from a sound recording of a single-line instrument using high-precision
audio-to-MIDI conversion software. Note onset times of pitch sequences are then plotted against the score-predicted timings
to produce a Note-Time Playing Path (NTPP). The score-predicted onset time of each sequentially performed note (horizontal
axis) unfolds in performed time down the page (vertical axis). NTPPs provide a visualisation that shows (1) tempo variations,
(2) repetitive practice behaviours, (3) segmenting of material, (4) precise note time positions, and (5) time spent on playing
or not playing. The NTPP can provide significant new insights into behaviour and cognition of music performance and may also
be used to complement established traditional approaches such as think-alouds, interviews, and video coding. |
