I have some wind chimes in the key of A minor 6/9 ACEFAB. I would like to get more chimes, but I want to make sure that they would be in harmony with what I already have. Any suggestions? The chime people offered two chime sets, F major 9 FACEFG or B minor 5/6/9 BDFGBC. I don't know if these would go well or not. Maybe it is just something they had in stock.
