Editing Semitone (section)

===Well temperament===
There are many forms of [[well temperament]], but the characteristic they all share is that their semitones are of an uneven size. Every semitone in a well temperament has its own interval (usually close to the equal-tempered version of 100 cents), and there is no clear distinction between a ''diatonic'' and ''chromatic'' semitone in the tuning. Well temperament was constructed so that [[enharmonic]] equivalence could be assumed between all of these semitones, and whether they were written as a minor second or augmented unison did not effect a different sound. Instead, in these systems, each [[Key (music)|key]] had a slightly different sonic color or character, beyond the limitations of conventional notation.
