	In [[just intonation]], 1/1 represents the base frequency from which an interval is measured.		In [[just intonation]], 1/1 represents the base frequency from which an interval is measured.

			In any [[temperament]], any [[comma]] [[tempering out\|tempered out]] by that temperament is equated with 1/1, and thus intervals that differ by that comma in JI become equal in that temperament. For example, [[meantone]] sends [[81/80]] to the unison, and thus [[81/64]] and [[5/4]], which differ by [[81/80]] in JI, are equated to the same interval.

			As an interval region, the unison usually refers precisely to the 0-cent interval. However, there can be a tiny difference between any two intervals that are practically "the same note" (more pedantically, an extremely small [[Unnoticeable comma\|comma]]), that might be considered a "unison" (or at least too small to be a meaningful interval). This range usually goes up to 3.5 cents, as that is the just-noticeable difference.
