There are stages guitarist go through in that quest of comping in a jazz style. Maybe if I put info in a game formant... more will get into and understand.... Anyway, usually start with open position chords, basic triads and 7ths.... Then we move on to movable and bar chords... still triads, 7ths and now maybe some 9ths. And we begin to realize there are different styles of chords... Maj., Min., Dom., diminished, whole tone and and my god chords built on different scales... Usually at this point we get into to it. We organize and develop movable chord forms built from all scale degrees with roots on 6th, 5th, 4th and 3rds strings. We get our inversions down, begin to search for hip voicings, begin to use arranging techniques to develop organizational methods to categorize and create terminology yada yada.... This all great and at some point we get to that point of where we know and can hear our fretboard and understand how chords are constructed.
Now we're actually ready to learn how to comp in a jazz style. When we see changes for jazz standards, any jazz tune. Unless there is a written out part, or something implying a specified part or style... The changes are usually simply giving you harmonic info. Telling you what harmonic concept and where the tune is pulling from. The source of harmonic and melodic concepts. ( need some history and lots of listening)
What's happened in the last 20 or 30 years is.... 1) the notation is getting sloppy... The changes are full of notational mistakes, miss spellings and the person or program doing the notation is unaware of what the changes actually mean... and 2) the players are also unaware of what the changes mean, the many approaches and methods of controlling implied harmonic content. ( What are the chord tones and tensions and what makes them work together).
So an example could be... changes are, Bb-7 Eb7, C-7 F7, Bb-7 Eb7, Abmaj7. There not telling you to play basic guitar chords... There simply giving you basic harmonic info to use with the melody and soloing... something to start with.
Your job as guitar comping is to recognize the chord patterns and with quick analysis with melody included.... decide on what approach and style your going to use. The actual change, Bb-7 really has very little to do with what actual voicing you play. Could be Bb- anything, as long as it works with approach your using to comp with. For most jazz players, it's simply represents a collection of pitches. The actual notes I play is determined by my lead line and how I voice below. I don't so much play chords... I play lines, melodies, counter melodies, groove melodies...voiced below from harmonic areas. As i say quite often, one chord change may represent a entire "Chord Pattern", and each new chord has a relationship with the implied harmonic area from my quick analysis, approach and style. Many times the original melody notes will not be in actual chords... But because there is an approach being used which usually reflects something fairly standard in jazz... It's never a problem... usually simply makes it sound like it should.
Depending on instrumentation, style and volume... there can also be a bass line going on, sometimes inner lines... but the majority of the time it all starts from the lead line.
So back to sample chord progression. Can have many analysis... but most common would simply be... Bb- to Eb7 and to Abmaj. Sub-dom. to Dominant and to Tonic. The C- can have duel function... be deceptive resolution of V7 to III- and then either related V7 or II- V7 of II- and on and on.... but usually as a jazz player it's simply a chord pattern. It's a sub-dominant area until the last V7 chord which then becomes typical V7 to I. here's a quick sample of changes...
I have to go... I'll continue later...Reg
