This is İlhan Babaoğlu. I play alto, tenor and soprano. I learned music all by myself but I'm frustrated 'cos I feel I always play only by ear and never have anything in my memory. In saxophone playing my goal was to play what ı was thinking. I accomplish this when ı'm in good mood but when in bad mood ı can miss some notes when improvising. I'm not academic, ı always played over what the radio played and know in memory the 12 major scales, the pentatonics and the blues scales, the rest is all by ear even the scales that ı don't know. I didn't study much arpeggios. What exercises would you suggest me to learn to be able to controll my playing aii the time. When ı miss a note I get depressed. Thank you so much!
