Rock Harp
David, just listened to "Butter Strut." NICE!
Let me ask you something: I've been spending some time experimenting with my harp, trying to duplicate guitar solo riffs and mimicing guitar solo sound. I'm running my harp mic through different effects pedals and processors, trying to find a unique style. Along those lines, I'm running into some challenges - mostly due to the tuning, note availability, and bend ability on non-bendable notes. (My newbie-izm is also coming into play, but I'm working on that, too).
If I'm going for this type of sound and style, should I consider alternative tunings? What about missing notes? How can I address the missing bends?
I think this might be an unorthodox style of play (maybe not, though). Is this a path with rock harp I should continue to explore, or am I getting the wrong idea of how to play in that medium?
It all gets down to easier access to each note of the chromatic scale. Again, this is uncharted territory, so you would need to get one and see how it helps you to play what you want to play. I recommend you try to copy one of your favorite rock solos (most likely on guitar) on your standard harmonica, then try it on the PowerBender and see which harp makes it easier to play.
P.S., something to keep in mind is when you change the tuning of a harmonica your chords change, so tongue blocking options also change (the easiest thing to look at is availability of octaves).
Good luck!
I have never heard a rock harmonica player play an altered-tuned harp. You could be the first! ;-)
Focus heavily on your bends... get those dialed in. After you have mastered all blow and draw bends (you've finished all of the bending study songs) look into studying overbends... this will make your harmonica fully chromatic.
There could be some interesting tuning options, but you're on your own there since it's never been done. You may want to check out Brendan Power's PowerBender.
Keep in mind that many have gone down the road of searching and designing tunings at the loss of practice time ;-)
