Microintervals Notation

OM offers all scales approximations from 1/2 to 1/8 tone, as well as 1/10, 1/12, 1/14 and 1/16 tone approximations.

All accidentals are ascending, that is, based on naturals and sharps .

Microtonal scales are not available in a tonal context.

To cancel the choice of a tonality, press Shift + t. The original "atonal" configuration is be restored.

Naturals are replaced by plain vertical lines – for instance : .

Incrementations of sharps are indicated by two vertical lines – for instance :.

• 1/4 tone scale :

  the number of vertical lines indicates incrementations of 1, 2 or 3 quarter tones – for instance .

• 1/8  and 1/16 tone scales :

  three different arrowheads indicate incrementations of a 1/16th , 1/8th and 3/16th tones of naturals and sharps.

• 1/3 tone scale :

  incrementations of 1 or 2 thirds of tone are shown by the number of additional horizontal lines – for instance .

• 1/6 and 1/12 tone scales :

  they combine arrowheads with horizontal lines.

• 1/5, 1/7 tone scale and their multiples :

  they use additional combination of horizontal lines.
