frickin. cordion. cant see the dang buttons. and theyre diagonal so it feels like the 7th for a root should actually be the 7th for the next row over. bonkers that it does that tho. bonkers you can play major minor and 7th chords with one button. if i got a 120 bass accordion instead of an 80 bass thered be a whole extra row with sus chords (i believe)
related: (tragic): need to learn the circle of fifths because its built into how the accordion works. smh
