Typically, intonation is a small interval between -50 ¢ and +50 ¢ | Typically, intonation is a small interval between -50 ¢ and +50 ¢ alhough larger values are allowed. In our model, the common tonic of all modes of the overtone scale has an intonation of 0 ¢ by definition. | ||
According to this definition'','' the upper pitch of the just major third above the tonic (Mode 4, see | According to this definition'','' the upper pitch of the just major third above the tonic (Mode 4, see [[#example01|Example 1]]) has an intonation interval of '''-14 ¢''', which represents the ''distance '''from''' the nearest vertical 12edo line''. Note that we generally measure intonation beginning at the nearest 12edo pitch. This results in a minus sign for the intonation of the upper note of the just third. | ||

The unusual definition of the sign is based on a technical point of view and takes into account the plan to build a real instrument. The signed intonation interval represents the amount of retuning required when a commercially available sound module is factory tuned to 12tet. | |||
