| I often find myself in the same situation described by the o.p., locked into the minor blues scale (or just the pentatonic w/o the b5) and looking for something different to mix it up. I'm really interested in hearing other folks' suggestions.
I've been trying to incorporate into my playing, especially in one- or two-chord jams, a couple of ideas passed on to me by a guy whose playing I really dig. One is to play for periods -- maybe just a bar or two, maybe longer -- without using the root. It's surprisingly hard to make yourself do, but it's extremely effective for building tension that, once you crash-land back on the root (on a big ONE), gets released and can propel the jam off in a new direction. (I especially like to do little triplet runs up or down between the 4 and 5 with the tritone in the middle.) The idea of leaving out the root is related to the suggestion of using different modes -- i.e., in which the root tone is in the scale but not so much a go-to note -- but doesn't require thinking about modes if that doesn't come easily or naturally to you.
The second idea is to use chromatic runs, especially in fours to or from the root. For example, do a little four-note walk from the b3 down to the root, or from the b7 down to the 5. This idea is used to great effect in the instrumental section of Pink Floyd's Money, in two different flavors: The walkdown over the tonic Bm chord starts on the root, then jumps to the b3 and walks back down toward the root, via 2 and b2, anticipating the next Bm. (There's actually a quick leading A tone to the first beat too, which adds a little extra rhythmic spice -- baDUM DUM DUM DUM, baDUM DUM DUM DUM). When the progression goes to the fifth (Em) chord, the chromatic walkdown starts on the root and walks straight down to the 6 (i.e., root-7-b7-6). Sometimes I'll use these exact riffs in a jam, if the groove and tempo are right, to explicitly quote this song for a few bars just for fun, but you can use different variations of the idea in almost any minor-key jam.
Don't know if that helps, but I hope others will chime in with more ideas. |
