Pythagoras, a Greek philosopher who lived around 500BC, is said to have discovered that notes that sound harmonious together have simple ratios between their frequencies: for example, one that is an octave higher than another has double the frequency.
Whatever the reason, women in polite company are required to speak with child-like voices an octave or so higher than normal.
My present editor at Faber's has yet to alert me formally that Seamus and I have had books appearing within the octave.
Today's electrodes do not reach very far into the spiral, which limits the perception of low frequencies".The case for upgrading will become more compelling as new types of electrode emerge".Tests of the intra-neural electrodes in cats suggest that they can stimulate frequencies as low as 600Hz a bit more than an octave above middle C on the piano, and much lower than traditional electrodes.
A glass of rich buffalo milk in the morning; then four hours singing a raga in the lowest octave as the first part of up to 20 hours of practice.
A gamelan may be tuned to the scale of slendro (in which the octave is divided into five tones roughly equidistant) or to pelog (a scale consisting of seven notes of varying intervals of which five are given principal stress).
For example, one Javanese slendro octave has the following intervals expressed in cents (a unit of pitch measurement; 1,200 cents make 12 semitones or 1 octave): 246, 241, 219, 254, 246; another has 245, 237, 234, 245, 267.
Its chanter is stopped on the knee both for staccato and to jump the reed to the higher octave, giving this bagpipe a melodic compass of two octaves (in contrast to the more common compass of nine tones).
The common sizes, built a fifth apart, were called (from highest to lowest) the treble, the tenor, and the bass, usually with corresponding pitches in winds of a, d, and G. Flutes and recorders were an octave higher.
