Figure 3. Wessell Anderson (alto saxophone), “Desimonae”
(a) The transcription approximates the soloist’s acceleration given the accompaniment’s steady tempo.
(b) An alternate notation re-interprets the rhythm as a series of eighth- and sixteenth-notes undergoing a gradual acceleration.
The concentric circles are omitted here because their radii depend on a single tempo, whereas this graph is a superposition of six different tempos.
