The distance from low do up to high do, the octave encompasses eight scalar tones ( do, re, mi, fa, sol, la, ti, do), as in, for example the white keys on the piano, C, D, E, F, G, A, B, C. This distance also encompasses twelve chromatic tones, represented by the white and black keys, as in C, C#, D, D#, E, F, F#, G, G#, A, A#, B.

Thus the note with a frequency of 512 Hz, is 1 octave higher then a note with a frequency of 256 Hz. ** A note that has overtones does not sound as pure as a note without overtones. ** As a wave gets more and more overtones, it is said to have greater wave complexity.

A frequency band consisting of any starting frequency extending up to a frequency twice the starting frequency. In an electronic context it is used to describe a filter's behavior such as attenuating three dB per octave.

Interval between two tones seven diatonic pitches apart; the lower note vibrates half as fast as the upper and sounds an octave lower.

A difference of pitch where one tone has a frequency that is double or one-half of the frequency of another tone.

The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 hz.

Two notes that have the same letter name but one of them will be exactly twice as high or low in pitch as the other one.

A doubling or halving of frequency. For instance, 50 Hz to 100 Hz is one octave, as is 20 kHz to 10 kHz.

the eighth position of the blade - see prime

to modern ears, the "same" pitch separated by register. The octave is the eighth note counting by step up a diatonic scale and in modern notation would be called by the same letter name as the starting pitch. Medieval listeners, however, did not consider octaves to be equivalent, so, for instance, a cadence on the upper octave could not be substituted for a lower note. See interval.

The interval between any two frequencies having the ratio of 1:2. The interval in octaves between any two frequencies is the logarithm to the base 2 (or 3.322 times the logarithm to the base 10) of the frequency ratio.

Eight notes, beginning and ending on the same letter name; double the frequency of vibration.

An octave is a doubling or halving of frequency. 20Hz-40Hz is often considered the bottom octave, 40Hz to 80Hz is the bass octave. 80Hz to 160Hz is the upper bass octave, etc.

The interval between any two frequencies having a ratio of 2 to 1. Example: "A 440" is an octave above "A 220".

pitch interval or frequency ratio of two to one. Thus, a jump from 50 Hz to 100 Hz is one octave, as is a jump from 5,000 Hz to 10,000 Hz (5 kHz to 10 kHz). In listening to musical programs, the interaction of ear and brain makes it difficult to resolve minor frequency-response anomalies narrower than about a third of an octave.

A one octave increase in frequency means doubling the frequency. A note one octave higher than another sort of sounds the same, but at a higher pitch. Play a one octave step from 440 (A4 standard for orchestra tuning) to 880 Hz. (180 kb wav file; requires patience). 1/3 octave smoothing means averaging the frequency response over 1/3 octave intervals. This smoothes out (i.e. obscures) abrupt changes in frequency response.

1. The interval of eight diatonic degrees between two musical tones. 2.The doubling or halving of frequencies.1000Hz is an octave higher than 500Hz.

A tone with either twice or half the frequency of another given tone, or eight "letter" tones span between such notes. Back to the Top

An octave is a doubling or halving of frequency. 20Hz-40Hz is often considered the bottom octave. Each octave you add on the bottom requires that your speakers move four times as much air

the interval embracing eight diatonic tones.

An interval indicated by two notes which have frequencies at a 2:1 ratio to one another. For example, the note A at 220Hz is one octave below A at 440Hz.

an interval (eg C3 to C4) sometimes called the "perfect" 8th because of the simple 2 : 1 frequency ratio

a frequency ratio of 2:1. A musical distance (interval) of 12 semitones.

The interval between a sound of one frequency and a sound with a frequency that is exactly double the first.

From the Latin Octavos an eighth. Octaves originate from music domain where 1 octave spans 8 notes, the 8th note is twice the frequency of the 1st note and the 9th twice that of the 2nd etc. This may be seen on the standard piano keyboard. It not often used in vibration analysisis.

The eighth of eight defensive positions in fencing.

A term to describe a series of notes on the musical keyboard which constitute eight distinct notes.

One full series of eight notes on the musical scale.

the range between two frequencies whose ratio is 2:1

The significance of octaves is that they are the same note - the only difference is the pitch. So, for any of the (sound) frequencies on this list, higher and lower octaves in theory could have the same effects that the original frequency does.

The difference in frequencies where one is twice the other. 200Hz is an Octave higher than 100Hz.

The interval between any two frequencies f 1 and f 2, when f 2 = 2f 1.

A doubling or halving of the frequency.

Full musical scale from one C to another C (or from any other note to another same note). A note frequency multiplied by 2 gives the same note one octave higher.

Frequency difference between harmonic vibrations; it is the doubling of the frequency of sound.

An interval of an 8th, with the lower and upper notes having the same letter name.

Frequencies related by a factor of 2:1 are said to be one octave apart. Musical tones whose fundamental frequencies differ by a factor of 2:1 are perceived as one octave apart.

Interval of eight notes, separating two notes with the same name in successive scales.

An interval eight diatonic scale degrees above it. Two notes an octave apart have the same letter name, and form the most consonant interval possible.

In musical terms, the eighth tone of an ascending or descending diatonic (major or minor) scale, or the interval created between one tone and another that is seven degrees in distance from the first in a diatonic scale

A frequency multiplier of 2.

A doubling or halving of a frequency. For example, 200 Hz is one octave higher than 100 Hz; 50 Hz is one octave lower.

In music, an octave (sometimes abbreviated 8ve or 8va) is the interval between one musical note and another with half or double the frequency.

Octave in liturgical usage has two senses. In the first sense, it is the eighth day following a major feast, particularly in the Catholic, Eastern Orthodox and Anglican liturgal calendars. In the late Middle Ages the second sense of octave developed as an eight-day festival with a specific liturgy.

The Moody Blues reformed in 1978 after a six-year hiatus to record Octave, the groups' eighth album. However, the album was the last for the group with keyboardist Mike Pinder, who departed after the album's sessions, declining an offer to tour with the group. As a result, the Moody Blues replaced Pinder with former Yes keyboardist Patrick Moraz in time for their 1979 tour.
