Aspects or methods of musical processing having intrinsic musical character, i.e. involving musical theory or musical parameters or relying on musical knowledge, as applied in electrophonic musical tools or instruments; Special musical scales, i.e. other than the 12- interval equally tempered scale; Special input devices therefor; Equally tempered scale, i.e. note tuning scale in which every pair of adjacent notes has an identical frequency ratio equal to 2 to the power 1/n if the scale has n notes per octave Huygens scale, i.e. 31 equal intervals per octave, provides near-just major thirds, and provides decent matches for harmonics up to at least 13, despite a slightly less accurate fifth than the standard 12 interval equally tempered scale
