). The original MuseData files can be converted into several other
musical data formats for printing (SCORE), audition (MIDI), and analysis
(Humdrum).
Example Analytic Use
Unlike traditional printed music, this edition also includes
the underlying data used to generate the printable scores in PDF format.
Computer applications can use this data for further processing such
as for music analysis.
For example, below is a graphical representation of the harmonic
structure for the first movement of the fifth symphony generated by
analyzing the symbolic form of the score. Each color
represents a different key (see color-mapping legend below plot),
with time progressing from the start of the movement on the left
to the end on the right. Throughout the movement the musical key
constantly changes. Brief visits to a key region generate small
color regions on the plot, while larger color regions indicate
more significant key regions.
The movement is in C minor which is represented by dark green in the
plot. The movement is in typical sonata form, with the first theme
in the tonic key (dark green), followed by the second key in the
relative major (E-flat major represented by the red color).
The development section progresses episodically through several
key regions (G minor, G major, C major, B-flat major, B-flat minor,
F-sharp minor, and D major, finally ending back in the tonic key
at the start of the recapitulation with a restatement of the first theme.
In typical sonata form, the second theme is transposed to the tonic
key. In this case to the major mode (C major) which is shown in
bright green on the keyscape plot. Finally an extended coda concludes
the movement in the tonic key.
