Hmm …
I want to create a song form as follows——

INTRO 8 BARS
HEAD 12 BARS REPEATED for a total of 24
SOLOS 12 BARS but different chords with optional # of repeats (if not possible then total of 48 bars)
REPEAT OF HEAD (24 bars)with the last 4 bars repeating 3 times (DS to Tag?)

Still trying to wrap my head around some of the BIAB terminology where it differs from standard musical terms … confused
