tritave造句

• A contra clarinet ( one tritave lower than the soprano ) is under development.
• Another example is the tritave of the Bohlen Pierce scale ( 3 : 1 ).
• An expansion of the Bohlen Pierce tritave from 13 equal steps to 39 equal steps, proposed by Paul Erlich, gives additional odd harmonics.
• "' A12 "'( ) is a non-octave-repeating scale or musical tuning featuring twelve steps to the tritave.
• Typically there is a fundamental tone, an overtone tuned to an octave above that fundamental, and an additional overtone a fifth above that octave ( twelfth / tritave ).
• Because the clarinet's spectrum ( in the chalumeau register ) consists of primarily the odd harmonics, and the instrument overblows at the twelfth ( or tritave ) rather than the octave as most other woodwind instruments do, there is a natural affinity between it and the Bohlen Pierce scale.
• An example of an equal temperament that finds its smallest interval by dividing an interval other than the octave into equal parts is the equal-tempered version of the Bohlen Pierce scale, which divides the just interval of an octave and a fifth ( ratio 3 : 1 ), called a " tritave " or a " pseudo-octave " in that system, into 13 equal parts.
• Dividing the tritave into 13 equal steps tempers out, or reduces to a unison, both of the intervals 245 / 243 ( about 14 cents, sometimes called the minor Bohlen Pierce diesis ) and 3125 / 3087 ( about 21 cents, sometimes called the major Bohlen Pierce diesis ) in the same way that dividing the octave into 12 equal steps reduces both 81 / 80 ( syntonic comma ) and 128 / 125 ( 5-limit limma ) to a unison.
