Piano is great for people who learned to play by sight.

Trombone is great for people who learned to play by ear.

For those who can easily hear the 13 cent difference between a justly tuned major third and an equally tuned major third, justly tuned instruments can be really hard to play.

But I am, like most, like you. I first learned on the piano and my ear is pretty bad for an experienced trombonist. I have a pretty good ear compared to the average person, but compared to a typical trombonist, it's really bad.

I play with others who have incredible ears. It makes me jealous.
