The '''Microtone''' is an [[interval measure]] that is sufficiently precise for all thinkable musical and music-science purposes. Besides its high accuracy, it is of a high neutrality since it favors neither twelve-tonality nor even the [[octave]].
The '''Microtone''' is an [[interval measure]] that can be considered as sufficiently precise for all thinkable musical and music-science purposes. Besides its high accuracy, it is of high neutrality since it favors neither twelve-tonality nor even the [[octave]]. Nevertheless its relevance for practical application in music is low due to the incompatibility with "[[human scale]]". Humans are not good at big numbers and have only limited pitch perception (the [[Just-noticeable difference]] (JND) is around 6 cents).


One actual microtone ('''1µt''') would be defined as one millionth of the [[tone]]:

A microtone is indeed a very small interval: 4904 microtones make one [[cent]], and 5884949 an octave.


Two sounds different only by 1µt produce a very slow [[beat]]; depending on the frequency one have to wait more or less to recocnize it. The beat frequency is
