I am a Music teacher. I hold a Ph.D. in Music Composition, studied piano for several years, and now I want to play the bass.
My concern is that every resource I find to become self-taught ends up covering very basic aspects of music theory (notes, scales, chords, functional harmony, rhythmic notation etc.) and it seems to overweight the importance of the very specifics of the instrument. I feel stuck into things I already have grasped for years, and just don't know what to skip, for fear of missing something technically important in such process. The outcome is very little advance into technical aspects and limited expression through the instrument.
Do you know any resources or strategies that could help me through this?
