    • n octave In music: A tone on the eighth diatonic degree above or below a given tone; the next higher or lower replicate of a given tone.
    • n octave The interval between any tone and a tone on the eighth degree above or below it.
    • n octave The harmonic combination of two tones at the interval thus described.
    • n octave In a scale, the eighth tone from the bottom, or, more exactly, the tone with which the repetition of the scale begins; the upper key-note or tonic; the eighth: solmizated do, like the lower key-note. The typical interval of an octave is that between any tone and its next replicate, which is acoustically represented by the ratio 1:2 — that is, in number of vibrations — and is equal to six diatonic whole steps or to twelve semitones. Such an octave is called perfect or major; an octave one halfstep shorter is called diminished or minor; an octave one half-step longer is called augmented. The perfect octave is the most complete consonance after the unison. Indeed, its completeness is often regarded as belonging to a different category from that of the other perfect consonances, except the unison, since it amounts rather to a repetition or reinforcement of the original tone at a higher or lower pitch than to a combination of a new or different tone with it: hence the term replicate. In harmony the parallel motion of two voice-parts in perfect octaves is forbidden, except where the mere reinforcement of one voice by another is desired: such octaves are called consecutive octaves. See consecutive intervals, under consecutive.
    • n octave In a standard system of tones selected for artistic use, a division or section or group of tones an octave long, the limits of which are fixed by reference to a given or assumed standard tone whose exact pitch may be defined. The tone usually assumed as a starting-point is middle C (written on the first leger line below in the treble clef, and on the first above in the bass clef). The octave beginning on the next C below is called the tenor or small octave; that beginning on the second C below is called the bass or great octave; that beginning on the third C below is called the contrabass octave; while that beginning on middle C itself is called the alto, once-marked, or once-accented octave; that beginning on the next C above is called the treble, twice-marked, or twice-accented octave, etc. See the accompanying table: The acceptance of the octave as the best unit for thus dividing the series of recognized tones into sections of equal length and value has not been uniform. Ancient Greek music seems to have first used the tetrachord as such a unit; while medieval music employed the hexachord in the same way. The subdivision of the octave portions themselves has also varied greatly in different systems of music. See scale.
    • n octave In organ-building, a stop whose pipes give tones an octave above the normal pitch of the digitals used; specifically, such a stop of the diapason variety. Also known as the principal. Also called octave-flute, octavestop.

In science:

With the division of an octave into 12 semitones, intervals may also be defined by number of semitones between the two tones.
Music in Terms of Science
The inversions of a chord do not alter the harmonic effect of it, because a tone sounds the same as its octave.
Music in Terms of Science
Those above octave can also be considered as a tone within an octave of one octave higher.
