What I can already do - identify all intervals, triads and sevenths, little bit sight singing. What I want to do - identify 9ths 11th and 13 th chords, identify chord progressions, identify polychords, play by ear any rock pop or film music, improvise well, transcribe complex piano and orchestral pieces, write compositions without need of piano, and sight singing in my mind. How do I learn to do this?😭 I don't have perfect pitch.
