what was the most improvement you've ever seen in someone's singing ability? mine is, when I was in pre-k, I could not sing for shit. I'd tell my mom to guess what I was singing and she legit wouldn't know and just guessed a song. she got me this computer program, singing coach, and I didn't leave the computer for weeks and by the end of it, she could actually tell what I sang and it sounded halfway nice (for a 5 year old singing baa baa black sheep)
Not singing, because everyone I’ve watched sing has improved in huge strides as they learn, but the biggest musical improvement is my mom.
She used to have literally no knowledge about music. None. Nada.
She can now accurately identify middle C on the piano about half the time. (No, Mom, it’s not the key between the pair of two black keys, that’s D, yes I know it seems more like the “middle” but that’s just because you like symmetry.)
