Регулировка гэпов для улучшения контроля бендов
Добавлено: Сб янв 15, 2011 11:57 pm
Кажется, в школах, выложенных на сайте, это не отражено совсем. Кроме того, довольно часто встречаются сообщения, что новички могут бендить, например, на гармонике в C, а на низких не могут и т. п. Поэтому и выкладываю этот текст, может, кому-то будет полезен. Да, переводить на русский язык влом, если что-то непонятно или есть возражения, пишите.
I don't know it's already written somewhere or not, but I want to tell about the dependence of bends from gaps on diatonic harps in different keys. Perhaps, it'll be helpful for someone.
Beginners often have problems with the pitch control on harps in different keys. Especially, on holes 2 and 3 (I mean a "standard" richter-tuned harp). Of course they have to be able to get the all bends on these holes, but, say, they can easily get the full-step bend on an A harp and can't get it on a D harp. Obviously, the technic of bends on A and D harps is slightly difference in mouth's configuration. But the gaps are also important.
I think all beginners which can bent notes have to learn how to regulate gaps for themselves. Bending an A harp on hole 2 or 3, we have to draw in more strongly so that two relatively heavy reads could start vibrating. So we can decrease the gap, therefore the airstream press on the reads in the hole will be grown, and the pitch control will be easier.
But for a D harp we have a different situation. The reads are lighter than ones in an A harp. If the gap is very little, the high pressure will press on the reads. So the bend pitch is very depended from the pressure, it'll be hard to contol the pitch. Propably, you will have to pinch your throat to decrease the pressure to get the needed note. It's very badly because it gives bad sound and wearies the throat. So the decision is to increase the gap.
Of course all we have different mouth physiology. You should try to find such gaps that allow you to get all bends accurately without throat overstrain. I think this approach is also related to blow bends and overbends.
