| Notes | "The first truly modern adaption of Leon Theremin's original instrument. The model 351 is basically identical with model 305. However in the model 351 two features have been added which greatly expand the versatility of the instrument. The first of these is the OVERTONE SELECTOR, a switch with which the performer may inject one of three natural (not tempered) overtones into the fundamental tone. These overtones do not appear as separate notes, but rather give the fundamental tone a quality remarkably similar to the vowel sounds made by the human voice. This is a feature not found in any other musical instrument, and is made possible by the advanced design developed by the R.A.Moog Co. |
