Re: Getting a more fusion-esque sound
Try more parallelism in your chord progressions. One of the big things in fusion is to get rid of the standard types of chord progressions found in earlier jazz like bebop and hard bop. The old II-V-I type progression were pretty much passe' when fusion came about. Instead you see alot more static chord progressions utilizing parallel block chords. That's one of many charateristics of the genre.
In some cases the harmony just seemed to be there for ambience. The harmonic structures didn't seem to be as closely tied to the melody as they were in more traditional styles. The chords just seem to push here and there. I would almost say the chords functioned more as a counterpoint/counter-melody than as a harmonic background.
Also try changing meters. Some fusion used odd meters like 7/4. It was not uncommon to have multiple meter changes in a composition. You would start out in one meter like 7/4 and the go to 5/4 then maybe backe to 7/4 and then to something like 6/8.
Also, try carrying the melody in an unusual instrument like the bass.
Try to incorporate world music into your playing. My favorite stuff is from Brasil. However, for fusion I think Samba would be a more compatible style than Bassa Nova or Brazilian Pop.
Listen to styles that came just before fusion to understand how fusion evolved. It always helps to know where the style evolved from. It gives you a historical perspective.
Pre-Fusion bands : Miles Davis Quintet, Freddie Hubbard, Woody Shaw, John Coltrane to name a few.
Pre-Fusion Artists: Miles Davis, Wayne Shorter, Herbie Han****, McCoy Tyner, Chick Corea
Listen to: Freddie Hubbard, "Take it to the Ozone" for some perfect pre-fusion.
Also McCoy Tyner, "Rotunda"
Some Fusion Groups: Return to Forever, Mahavisnu Orchestra, Jean Luc Ponte, John Scofield, Ornette Coleman, Jack DeJohnette, Pat Metheny, John Abercrombe to name a few.
