'''Tempering out''' is what a [[regular temperament]] (including rank-1 temperaments ~~aka~~ [[equal temperament]]s) does to a small interval like a [[comma]]: it makes it disappear, or as some authors put it, ''vanish''.<ref>''Vanish'' is notably used throughout ''[[A Middle Path]]''.</ref>

'''Tempering out''' is what a [[regular temperament]] (including rank-1 temperaments a.k.a. [[equal temperament]]s) does to a small interval like a [[comma]]: it makes it disappear, or as some authors put it, ''vanish''.<ref group="note">''Vanish'' is notably used throughout ''[[A Middle Path]]''. However, ''vanish'' is broader than ''temper out'', as any abstract interval can ''vanish''. For example, you could say "in [[5edo]], the small step of the [[5L 2s|diatonic scale]] vanishes" without specifying a just interval at all. In this sense, ''being tempered out'' is a specific way of ''vanishing''. </ref>

~~== Overview ==~~

For a tone measured as a [[ratio]] to disappear, it must become equal to 1/1, so that multiplying by the ratio does not change anything. For a tone measured in [[cent]]s to disappear, it must become 0 cents, so that adding it does not change anything.

For a tone measured as a ratio to "disappear", it must become equal to 1/1, so that multiplying by the ratio does not change anything. For a tone measured in ~~cents~~ to "disappear", it must become 0 cents, so that adding it does not change anything.

In both cases, that implies that we are introducing some error into our tunings: where we would use 3, for instance, we use a number slightly larger or smaller than 3. You can introduce error into any prime, and when tempering out a single comma you can choose to leave any given prime pure. In practice, many people leave 2 pure to achieve pure octaves. There are also options to temper the octave, such as [[TOP tuning]].
