Musical scale

See also: Scale

In Music, a scale is a whole of Fréquence S - sounds or height S, usually called degrees - fixed by a musical system given . A musical scale is mainly characterized by the joint intervals which compose it - i.e., intervals between close degrees -, and this, independently of any idea of tonic Tonalité and . Incidentally, and when that is possible, a musical scale is also characterized by the denomination of its various degrees - the name of the notes.

  • Any scale musical being necessarily associated with a culture, with a Civilization, a musical system, a Standard of music, obviously it would not know to exist of “universal scale”, nor of “natural scale”.

  • There thus exists all over the world, a very great number of scales, very of different structures: those pertaining to a more or less remote past - musical scales of the ancient Greece for example -, those pertaining to the musical systems of others Culture S - musical scales of the Arab countries, of India, of China, the pentatonic scales present in many countries -, or, those imagined of any part by musicians wishing to break with the tradition - cf scale by let us tons whole. Some of these scales can be made up of joint intervals lower than the Demi-ton, others, on the contrary, intervals higher than the your.

One will note that in the Western music, the qualified scale of natural Gamme, is, in spite of his name, as artificial as the others. Its misleading name is explained by the fact why its structure uses a certain number of reports/ratios of Fréquence contained in the Harmonique S of the sound: however, only this last phenomenon - which as for him, raises of the Acoustique - can be regarded as “naturalness” and “universal”.

  • the scale prototype of the tonal Système - as that of the modal system, moreover - is the diatonic scale, made up of let us tons and of semitones diatonic. In this system, the chromatic scale, made up exclusively of Semitone S, must be analyzed like a extension of the diatonic scale, the intermediate notes sharing each tone playing only one decorative part.
