Tip: you don't have to recognize sounds in order to compose music.

I have aphantasia and can't memorize sounds or recall them. For decades I thought I'm deaf (Ockham say hi). But I picked up piano, play for 3 years, can't discern C from G if my life depended on it but my friends tell me I'm pretty decent composer.

Writing this so people don't get disappointed about themselves just because they can't pick ear skills.

I've been doing these exercises regularly for years and haven't made much progress ;). I still perform music regularly and get positive feedback. I do hope that some day I'll get to where these exercises seem easy - I haven't made much progress, but I do make a tiny bit at a time.

can you tell if a piano is out of tune? I'm curious since I don't know anyone with aphantasia. Can you tell if someone is playing your composition correctly?
