so i've been working on a huge full chord transcription of 'history of the entire world i guess' a few of them were really difficult so i wanted to ask. 1. for 'cambrian explosion' i got "Abmaj9, C#add9/Bb Badd9" is that right? these are really old transcriptions and the chords are akwardly notated so it might be wrong/hard to understand.
that looks close, but these things are arranged very tightly. here is the original writing demo, from july 1, 2016
