Chord symbols (accordion): a bass tone and a chord simultaneously
I would like to wrtie some music for piano accordion (Stradella Bass).
Is it possible to have two accord symbols simultaneously and above each other.
As in the attached example: a G bass tone and a G major chord (lowercase!) at the same time.
How could I write this as one chord symbol? The bass tone as one voice and the chord as a second is a bad idea, because I will never have differences in the durations ...
Thanks for your help in advance!!!
