Very nice progression...makes a great jam...throw in a 7th on your Cm and you'll get some butter with that jam
Thanks for the listen Firesong.
My keyboard skills are very basic, and my bass skills not much better. If throwing in a 7th means adding an additional note, that could be challenging. Moving from one 3-note cord to another for the brass section took several attempts to get right; not sure if a 4th finger would decide to cooperate
Although, I always wanted to play piano as a kid; but we never had the money.
