I sometimes use my 'eleventh finger' ....
...... and returning to the topic: I still don't understand the advantage of OT. I've been fiddling with this now since Monday, and I have a question for all you guys. When you UT in a passage, say a scale, does your wrist lurch? or do you bend thumb and smoothly pass it under other fingers without moving wrist?
My wrist moves not at all, or maybe just a teensy imperceptible bit. Following the Whiteside principles, I do "draw circles" a lot with my wrist as I play, but there's still no lurching. Maybe I have long thumbs??? and you know what they say about guys with long thumbs!!
...... he can't wear normal size gloves! hehe
anyway, perversities aside ... I'm really curious about this.
