Hello everyone. I have just joined this forum and am looking forward to participating. I have been visiting the Jazzguitar.be web site for about a year now, and find it
extremely good. Dirk has created a tremendous resource for us all.
I have been playing guitar from quite a while, mostly classical and instrumental versions of some classic rock, folk, country, and jazz standards. I play finger style, and sometimes develop my own arrangments (melody and accompaniment played together). I do this either by ear (for simple tunes) or by adapting sheet music that has the melody and chords. I find improvising jazz a challenge. It always comes out like blues - which I like, but want to expand my horizons. I have tried using Ted Greene's Single Note Soloing Vol.1, but can't seem to get his exercises working for me musically. Perhaps it's a bit too advanced for me at this point. I am planning to work through the Mickey Baker method, and use Michael Joyce's material as a supplement.
Does anyone have any thoughts on the necessity/importance of learning a lot of scales (modal, bebop, altered, etc.)?

My uneducated guess is that scales should take up a minor portion of one's learning time. Surely, one can develop good improvization skills by creating lines consisting of chordal tones linked by in-between notes, found by ear. If this is wrong, I'm willing to listen to reason!
