Learning by ear doesn’t feel more complete to me. I would never want to learn Debussy’s piano works by ear, for example. I don’t want to internalize anyone else’s interpretation. For important literature I want to use my own imagination, not someone else’s. I don’t want to listen to the audiobook version. Reading is about bringing yourself to meet a work. Another person’s reading is about their life, their emphasis, their resonances, not mine.
The time I’ve spent immersed in a page of text, making it into sound, like images coming to life when you read Dostoevsky or whoever, these are some of the best experiences we have access to as human beings, as far as I’m concerned. I do plenty of playing by ear as well. I would never waste my time reading a Charlie Parker transcription, for example- it’s all plainly audible on the recordings.
I don’t crown either my ear or my eye as “king”, personally- I’m a whole person. Why would I want to reduce the full sum of what capabilities I have?
