Your DC sounds very talented. So far, mine has confined himself to solo piano compositions because until now, it has been the only instrument he can play, although (speaking of random activities), two weeks ago, he picked up his older sister’s abandoned guitar & tuned it up to teach himself to play. He’s decided that the string instruments would be much more versatile for exploring harmonics & intends to use the guitar as a stepping stone to the violin (at which DH is quite proficient).

I have previously suggested that he should compose for multiple instrument voices but I think writing solos currently reflects his general preference to do things solo, but it’s a good suggestion, thanks!
