The '''merry tritone''', '''357/256''', is a close approximation to 12\25, hence the name. It is also a rather good approximation to [[32/23]] at about four cents (or [[8211/8192]]) away. | The '''merry tritone''', '''357/256''', is a close approximation to 12\25, hence the name.

== Terminology and notation == | |||
Conceptualization systems disagree on whether [[17/16]] should be a [[diatonic semitone]] or a [[chromatic semitone]], and as a result the disagreement propagates to all intervals of [[harmonic class|HC17]]. See [[17-limit]] for a detailed discussion. | |||
For 357/256 specifically: | |||
* In [[Functional Just System]], it is a diminished fifth, separated by [[4131/4096]] from the [[1024/729|Pythagorean diminished fifth (1024/729)]] less a [[64/63]] | |||
* In [[Helmholtz-Ellis notation]], it is an augmented fourth, separated by [[2187/2176]] from the [[729/512|Pythagorean augmented fourth (729/512)]] less a [[64/63]]. | |||
The term ''merry tritone'' omits the distinction and only describes its melodic property i.e. the size. | |||
