Lee Barry Composition Diary

 

Is there a standard schema (yet) for chord symbols, whereby any voicing can be expressed alphanumerically and be machine readable? For example, I had an odd chord that I was using the other day, and it wasn't clear how to write it. Would it be written "F-6/9" (as in jazz) or "Fmin6 (add 9)"?  A standard symbol mask could be:  pitch_M/m_(extension1)_(extension2) Examples: D(2) D(6,9) Dm6 Dm(6,9) D(9) DM7 DM7(+11) Dm7 D7(+9) D7(-9) D7(+5,+9) D(-5) Diminished D(+5) Augmented Dm7(-5) D9 D11 D13
