pythagorean apotome造句

The Pythagorean limma and Pythagorean apotome are enharmonic equivalents ( chromatic semitones ) and only a Pythagorean comma apart, in contrast to diatonic and chromatic semitones in meantone temperament and 5-limit just intonation.
I'll ask the guys on the tuning list if any other interval is called an apotome, but the only one I know of is 2187 / 2048, the Pythagorean apotome . Keenan Pepper 04 : 59, 21 January 2006 ( UTC)
In Pythagorean tuning, seven semitones out of twelve are diatonic, with ratio 256 : 243 or 90.2 cents ( Pythagorean limma ), and the other five are chromatic, with ratio 2187 : 2048 or 113.7 cents ( Pythagorean apotome ); they differ by the Pythagorean comma of ratio 531441 : 524288 or 23.5 cents.
The Pythagorean comma can be also defined as the difference between a Pythagorean apotome and a Pythagorean limma ( i . e ., between a chromatic and a diatonic semitone, as determined in Pythagorean tuning ), or the difference between twelve just perfect fifths and seven octaves, or the difference between three Pythagorean ditones and one octave ( this is the reason why the Pythagorean comma is also called a " ditonic comma " ).
