Harmonics

Science / Astrology / Harmonics: The term for zodiacal aspects that describe the energy levels or vibrational frequencies associated with aspects. An aspect, derived from the division of a circle (360°) by a whole number, and its multiples share the same frequency and therefore operate at similar energy levels. For example, division of 360° by four yields 90°, a square. The square is a fourth harmonic aspect as are its multiple, 180° (opposition) and 270°. Several harmonics may merge in a single aspect. The square is a multiple of the semi-square (45°), an eighth harmonic aspect; the square's primary harmonic is four (sometimes written 1/4) and its sub-harmonic is eight (2/8, second of the eighth harmonic). The opposition's primary harmonic is two (1/2 x 360°= 180°); its sub-harmonics are four (2/4, second in the series of fourth harmonics), six (3/6, third of the sixth harmonic), eight (4/8, fourth of the eighth harmonic), etc.

Overtone

Technology / Home Audio / Overtone: Similar in concept to a harmonic. Overtones are sounds produced by an instrument (or sound source) that are higher in frequency than the fundamental frequency. They may or may not coincide with the fr MORE

Octave

Technology / Home Audio / Octave: In audio, the interval between any two frequencies having a ratio of 2 to 1. One octave up from 100 Hz is 200 Hz, where one octave down from 100 Hz is 50 Hz. A harmonic is a doubling (2nd harmonic), t MORE

Overtide

Science / Tides and Currents / Overtide: A harmonic tidal (or tidal current) constituent with a speed that is an exact multiple of the speed of one of the fundamental constituents derived from the development of the tide-producing force. The MORE
