In music composition, the arrangement of a piece
typically follows a gradual introduction, a main
body with the core content, and a gradual conclu-
sion, also called the sonata form (Webster, 2001).
Accordingly, we look into whether our generated
music also shows such a long-term structure. Us-
ing the same text prompt, we can generate different
segments/intervals of it by attaching the expression
“1/2/3/4 out of 4” at the end of the text prompt, such
as “Italian Hip Hop 2022, 3 of 4.” We randomly
generate 1,000 music pieces, where the prompts
are from a uniform distribution of the four segment
tags. We visualize the results in Figure 6, where
we see the first segment shows a gradual increase
in both the average amplitude and variance, fol-
lowed by continuously high average amplitude and
variance throughout Segments 2 and 3, and finally
concluding with a gradual decline in the last seg-
ment.
