I was wondering if you who feel you cannot play by ear are able to sing, hum or whistle a tune? One of my exercises is to take a very simple tune like Twinkle…Star, and play it starting on every note of the chromatic scale from the lowest B flat to the G# that sits on the top line. Sometimes I have to fish around to find the right note, but less and less as I learn the scales. So, if I start on C, I know that if I am about to hit a sharp or flat note it probably won’t fit. Also, as I have struggled with scales, I have learned that if I just close my eyes and play do-re-mi-so… on my horn like we were taught to sing it in grade school. Then I can go back and “read” the scales. It seems a little backwards but we all learned to understand and speak words (verbal notes) and phrases (verbal scales, chords and licks) before we learned to read words. So what is backward, really? In the end the only way to progress is to get as much help as we can and find our own ways to improve.
