the term

Used in western musicWhole scaleBetween the sound with a frequency ratio of 2:1Whole tone5 intervalsSemitoneDivided at two intervalsSeven-tone scaleIs. In Western music, since the same degree is counted as one pitch, the pitch to reach the same note with different pitch in the seven-tone scale is 1 degrees. The Latin word for "8th = 8th pitch" is "octavus", from which it was derived and established in other languages ​​such as French "octave", English "octave", and German "Oktave".

Since octave simply means the eighth pitch, strictly speaking, it includes 8 degrees, 8 degrees, 8 degrees, 8 degrees, 8 degrees and 8 degrees. It means the pitch and the sound that separates the pitch. Sometimes it means not only one octave as an eighth note, but several octaves such as two octaves and three octaves. In addition, the term octave may be widely applied to pitches with a frequency ratio of 8:8 even in cases other than the seven-tone scale.

In India, the word equivalent to octave is the word “saptak”, which means 7. This is because one saptaka contains seven sounds (Sa, Ri, Ga, Ma, Pa, Dha, Ni), but unlike Western music, the same degree is counted as 1 degrees. This is because


A certain sound 2±nTimes (n:Integer) Frequency sound is recognized as the same kind of sound as the original sound,Human capitalIt has absoluteness as a common sense. One of the reasons why they are perceived as being essentially the same sound, although they have different pitches, is that it is contained in many sounds that exist in nature.Overtone, It is considered that the sound of the frequency of this relationship resonates as a basis, and the simplicity of the frequency ratio between two notes with different octaves is considered.[By whom?].

In many cultures, it has been expressed as the same note name because of the nature that sounds related to an octave can be heard as the same kind of sound at different pitches. For example, in Western music, the A sound is one octave above the A sound. The same is true for classical Indian music, and one octave above the Sa sound is the Sa sound. As another case, in Ottoman classical music (Turkey), one octave above the sound is called without giving the same name. For example, the sound one octave above the sound called Yeh Gaha is called Never. This is associated with continuing the musical theory tradition from ancient Greece.

Problems at the boundary between single and double pitches

In order to make it easier to understand the relationship, pitches over octave or higher are sometimes referred to as pitches shifted in octave units. At that time, a pitch below 8 degrees is called a single pitch, and a pitch over 8 degrees is called a double pitch. For example, a 17th pitch becomes a single 3rd pitch.

Eighth is a single pitch or a double pitch. When 8 degrees is considered as a compound pitch, it becomes 8 degree in a single pitch.

Two octaves are 2 degrees (quindecimo) instead of 16 degrees (diciasettesimo). In the case of an instruction to move 15 octaves higher,15ma altaor15ma,15but bor15ma lowIs written. HoweverMessiaenAlthough composers of the same generation, such as, respected the visibility as a number that is double that of 8, sometimes dare to write this as 2 degrees, but most modern composers use 16 degrees.
