Hi!
I'm writing python code to automatically annotate jazz solo transcriptions
(with their corresponding chord progressions) and to produce midi output using
Lilypond. I'd like to instruct Lilypond to lower the volume of the chord
progression with respect to the melody, but haven't been able to find a
solution. Any advice would be welcome!
Here is a sample of my Lilypond code:
\include "swing.ly"
\version "2.24.1"\language "english"
\header { title = "Untitled Tune I"
composer = "Charlie Christian"}
chord_progression = \chords { \set chordChanges = ##t
df1 df1 df1 df1 gf1:7 gf1:7 df1 df1 af1:7 af1:7 df1 af1:7 }
melody = \fixed c'
