(3) A progression of musical notes that comprises all the basic notes-C (do), D (re), E (mi), F (fa), G (sol), A (la), and B (si) -or the 12 semitones of the chromatic scale. (2) The eighth step of the diatonic scale. The octave is named after the Latin word for eight, octo. In other words, if you play the first note in an octave and then play the next note up, that is an octave. One octave equals 1,200 cents or 301 savarts. An octave is the distance between two tones that are 8 notes apart. This corresponds to the ratio of the upper cutoff frequency to the lower cutoff frequency, which equals 2( f 2/ f 1 = 2). From the acoustical point of view, an octave is the interval between two frequencies f 1 and f 2, the logarithm of whose ratio to the base 2, in other words log2 ( f 2/ f 1), is equal to 1. (1) An interval encompassing the eight steps of the diatonic scale or six whole tones.
