Earlier quoted context omitted.
Did it help your son to study music?
I'm not sure I understand the question, but I can answer both interpretations: 1. Did it (the chord trainer app) help my son when he was studying music? Not as far as I can tell. He has also been taking piano lessons and sometimes it helps a little with music theory to tie it back to the chords, but I don't think there's much transfer learning going on. He seems to have a good ear, but my other son is not picking up…
I'm asking because my sons started picking up piano lessons. I think the way their piano is taught relies to much on their eye. They are looking at music much more than listening to it. So am curious if there are ways to trigger their interest in hearing.
Again thanks for your reply!
