octave designation

The octaves are labeled from lowest to highest, beginning with 0 and continuing in ascending numerical order (1, 2, etc.). A piano keyboard primarily uses the ASPN octave designations 1 through 7, although small portions of octaves 0 and 8 are included. Middle C is C4 in ASPN.

ASPN and Octave Designations The octaves are labeled from lowest to highest, beginning with “0,” and continuing in numerical order (“1,” “2,” “3,” etc.). The pitch middle C is C4, which is useful to memorize. Example 2. The notes C4, D4, E4, F4, G4, A4, and B4.

An octave is a series of eight notes in a musical scale. It is also used to talk about the difference in pitch between the first and last notes in a musical scale.

An octave refers to the interval between one frequency and its double or its half. There is one octave band between frequencies 1 000 Hz and 2 000 Hz. There is another one octave band between 1 000 Hz and 500 Hz.

Pitches are named by using the first seven letters of the alphabet: A, B, C, D, E, F, and G. We will approach the nota- tion of pitch by relating this pitch alphabet to the keyboard, using Cs as an example. The C nearest the middle of the keyboard is called middle C, or C4.

The next pitch is called the octave because it's the eighth note (just as an octopus has eight legs). More than a thousand years ago the letters of the Roman alphabet were adopted to refer to these, and since there were only seven the letters ran A, B, C, D, E, F, G.

From a mathematical point of view, we can easily explain why 12 works nicely. The Greeks realized that sounds which have frequencies in rational proportion are perceived as harmonius. For example, a doubling of frequency gives an octave. A tripling of frequency gives a perfect fifth one octave higher.

Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB. It may also be used as a batch-oriented language.

: the difference in sound between the first and eighth note on a musical scale. He sang the song an octave lower. The two tones are (spaced) an octave apart.

The word "octave" comes from a Latin root meaning "eight". It seems an odd name for a frequency that is two times, not eight times, higher. The octave was named by musicians who were more interested in how octaves are divided into scales, than in how their frequencies are related.

Each octave up doubles the frequency- one octave above 300 Hz is 600 Hz; an octave up from there is 1200 Hz.

The octaves are named from one C to the next higher C. For example, all the notes in between "one line c" and "two line c" are "one line" notes. The octave below contra can be labelled CCC or Co; higher octaves can be labelled with higher numbers or more lines. Octaves are named from one C to the next higher C.
