I'm trying to find a..."reliable" is the word I'm looking for, I guess, to improvisation. I recognize that there is no single answer: one can work from the melody, chord scales, insert lines, or pieces of lines, from stuff you've learned, etc., etc., and approaches I've never even fathomed. But all that said, I'd like a starting point for hearing the song, looking at the chart, and being able to take a solo over the changes for a chorus or two. Lately, I've been treating each chord individually, and playing the arpeggio, sometimes adding chromatics, and often playing the triad within the chord, eg, Em for CM7, or Bdim for G7 -- and there's a ton of meat here. The problem I'm getting is everything sounds like I'm playing an arpeggio for each chord. Maybe I'm inserting an unconscious pause, but nothing sounds like it's flowing between chords. This isn't the case, if I just noodle around with, a parent major scale -- there's some fluidity you get from just working up and down a scale.... I'm curious how others are able to develop lines from the arpeggios without sounding disjointed. Also, I've heard, "never start on the root!" Why? Thx!
