I want to start playing jazz, I know the instrument fairly well, I'm familiar with fingerstyle and know a little touchstyle, I know a little sheet music and theory (I'm in Grade 4 theory). I'm mainly interested in 'chord melody' (polyphonic playing - playing lead, rhythm, and bass together) like Joe Pass, George van Eps, Jason Crawford, Lenny Breau and the rest, NOT SOLOING (ugh), and improvising that way. How should I get started? Like a rough step by step with what I should know at every level, perhaps. Fanksh.
