Semitone diatonic

In the Musical theory, the semitone diatonic indicates a category of Demi-ton pertaining to the diatonic scale, and located between two notes of different names.

It is called thus because, just like the chromatic Demi-ton, it is practically equal to half of the your.

• the natural diatonic scale contains two semitones diatonic: “ semi-F ” and “ if-C ”.

• the deterioration S allow, while adding or by withdrawing a chromatic semitone, to transpose these two semitones diatonic, with a unspecified height of the scale.

For example: “ semi $\backslash \; flat$-fa$\backslash \; flat$ ”, “ si$\backslash \; sharp$-do$\backslash \; sharp$ ”, “ Remi $\backslash \; flat$ ”, “ do$\backslash \; sharp$-ré ”.

• They also make it possible to transform a semitone diatonic into tone.

For example: “ mi$\backslash \; flat$-fa ”, “ si-do$\backslash \; sharp$ ”, “ mi-fa$\backslash \; sharp$ ”, “ si$\backslash \; flat$-do ”.

• the tone, the semitone diatonic and the chromatic semitone, are the basic intervals, the joint intervals, which by addition, makes it possible to obtain all the other intervals: third, quad, fifth, etc the semitone diatonic corresponds very precisely the interval of second minor.
