Ray Beltran, writing about the San Jose Harmonica Masterclass, writes:
None of the players who spoke used overblows, with the exception of Lee Oskar, and a few of them just plain said they didn't know how to do it, and weren't embarrassed to admit it. They'd rather just reach for their chromatic.
Actually, Lee does not use overblows. On the other hand, I do (just ask Hugh), but my seminar was about chromatic, so the subject did not come up.
But, unlike other instruments, not being able to graphically show the technique, aside from a few drawings taken from David's books, was painfully obvious. All weekend long, it was "Well, you just gotta pull from down here and it sounds like this..."
You must have missed my blues chromatic seminar, Ray (sorry to toot my own horn, but nobody else seems to be doing it). I used a giant tuning chart, and pointed to exactly what I was doing as I demonstrated some of the techniques. Next year, maybe computer animation and a projector.
By the way, this was an excellent event, if not as varied as SPAH (Ray correctly observes that the emphasis was almost entirely on blues). It's doubled in attendance from the first year to the second, and went off without a hitch (except for the police cordoning off several streets due to an "alternative" music festival and delaying our access to the evening club by several hours.)
Early in my seminar, David Barrett walked up with a wireless lapel mic and offered it - gladly accepted, as I was pacing about the stage between tape deck, keyboard, harp kit, and tuning chart, and the only onstage mic was one of those retro chrome-grilled fist-sized boxes on a fixed stand mounting that look like something out of Evita. What a joy to forget about holding a mic, not tripping on the cord, putting it on the stand, etc. I just may invest in one of these babies.
I look forward to next year's Masterclass. The way Dave and crew are going with this, it's headed to being one of the major world harmonica festivals.
