(EN) BICAMERAL SCALE MUSICAL INTONATIONS AND RECORDINGS MADE THEREFROM

Abstract
(EN)
This application relates to various stepped pitch instruments crafted to a novel musical tuning system for the generated frequencies. As such, the tone selection devices are arranged to a distinct set of interval specifications when compared to the tone selection devices for a prior art instrument crafted to sound the common frequencies of 12 tone equal temperament. To generate the bicameral tones, the preferred tuning system utilizes two different series of Pythagorean perfect fifths separated by a known reference interval. Relative to 12 tone, the instant tuning system is primarily concerned with improving the sour major and minor thirds and perfecting the slightly flat fifths. Substantially fewer tones per octave are used than the number required by standard just intonation. Various modifications to existing prior art instruments are described, as well as a novel enharmonic multitone keyboard.

L'invention se rapporte à divers instruments à tonalités en escalier conçus, en ce qui concerne les fréquences générées, conformément à un nouveau système d'accord musical (Fig. 2). Les organes de sélection des tons sont disposés selon un ensemble distinct de spécifications d'intervalles en comparaison des organes de sélection de tons d'un instrument fabriqué de manière conforme à l'état antérieur de la technique pour émettre les fréquences communes du tempérament égal à 12 tons. De manière à générer les tons bicaméraux, le système d'accord préféré utilise deux séries différentes de quintes parfaites pythagoriciennes, séparées par un intervalle de référence connu. Relativement aux douze tons, le nouveau système d'accord est principalement conçu pour améliorer les mauvaises tierces majeures et mineures et parfaire les quintes légèrement diminuées. On utilise sensiblement moins de tons par octave que le nombre requis par l'intonation juste standard. L'invention se rapporte à diverses modifications apportées aux instruments existants, ainsi qu'à un nouveau clavier multitonal enharmonique.
