Accordion chord notation with chord playback
I am learning accordion and have just started transcribing my first accordion piece, "Let my Baby Ride" by Doctor L (RL Burnside Cover)- Holy Motors OST.
I am trying to get playback on the chord but keeping with accordion notation standards of only notating/showing the root chord note.
Using Chord Notation with playback is not practical because the Chord Symbol require the note name (e.g. Em) whereas standard accordion notation only lists the accord type above the note, M/m/7/d (and then the playback sound is piano, not accordion).
I experimented with various other options (e.g. adding 3rd/5th as chord intervals) but in the end, the best option I could come up with, was to put root note in voice 1, put 3rd and 5th/7th in voice 2, keep them visible in the score, which allows me to hide them when creating the accordion part. There are some issues with this approach
1 mostly display / cosmetic issues in the score, like voice 1 stems face up, voice 2 stems face down
2 Transposing the score will not transpose the chord names (something that would have been solved with using proper Chord Notation)
How are others doing accordion chord notation with playback?
