To learn that instrument, I am following Kip Rosser's lessons: http://kiprosser.com/ I like his approach based on experimentation. The first lessons present the fundamental techniques. As example, the lesson 12 show a left hand technique which allow to make a vibrato like effect with the volume, resulting in successive pitches. Lesson 20 show the vibrato technique for the pitch. I think the main difficulty when playing a theremin, as we get a concert piano range into something like 50 to 60 centimetres, and no other mean to know where are the notes than our earring, is the resulting constant imprecision of the pitch. A good theremin player will succeed very well to mask it. Another difficulty is than for a guitar player like me, pitches in the C1 to C2 range or C7 to C8 range are very extreme ear training. The C7 to C8 range is the worst because the antenna cease to be linear at that distance (only a few centimetres from the antenna) and that octave is shorter than the others. At the same time, this is what make that instrument so fun. With the null of the pitch, you get a barrel like shape at 50/60 cm from the antenna, it have a few cm more width at the center of the antenna than at its extremities. This is our instrument and when playing it, it will react from all directions and with any part of your body. I can change the null and set it at only a few centimetres from the antenna. With such a setting, it is very weird to play, also because I can add pop like sounds between the pitches by touching the pitch antenna. Also it seam to have a terrific sound, because a neighbour tell me than he can ear me when I play it in the basement, with him in the house opposite making music with a computer and his headphones. For that, to play a theremin is worst than to play bass, you get a powerful sound but on the whole audio range. > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user@xxxxxxxxxxxxxxxxxxxx > https://lists.linuxaudio.org/listinfo/linux-audio-user -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
