	'''Buzzard''' is a [[regular temperament\|temperament]] that splits a tempered [[3/1\|perfect twelfth (3/1)]] into four [[generator]]s of [[21/16]] subfourths, [[tempering out]] the [[buzzardsma]] ([[ratio]]: 65536/64827). Two generators therefore give us a [[semitwelfth]], and five give us a sub-octave just short of the [[~~2/1\|~~octave]] by a [[64/63\|septimal comma]]. Bending the semitwelfth up by a septimal comma results in ~[[7/4]], and down results in ~[[12/7]], with the implication that the septimal diesis of [[49/48]] is equated to two septimal commas. In fact, buzzard slices the [[256/243\|Pythagorean limma]] into four, one for 64/63, two for 49/48, and three for [[28/27]].

This equates the [[81/80\|syntonic comma]] with the septimal comma and turns it into a generic comma step that can be used to bridge Pythagorean intervals with both classical and septimal intervals.

	'''Buzzard''' is a [[regular temperament\|temperament]] that splits a tempered [[3/1\|perfect twelfth (3/1)]] into four [[generator]]s of [[21/16]] subfourths, tempering out [[65536/64827]].

'''Buzzard''' is a [[regular temperament\|temperament]] that splits a tempered [[3/1\|perfect twelfth (3/1)]] into four [[generator]]s of [[21/16]] subfourths, [[tempering out]] the [[buzzardsma]] ([[ratio]]: 65536/64827). Two generators therefore give us a [[semitwelfth]], and five give us a sub-octave just short of the [[2/1\|octave]] by a [[64/63\|septimal comma]]. Bending the semitwelfth up by a septimal comma results in ~[[7/4]], and down results in ~[[12/7]], with the implication that the septimal diesis of [[49/48]] is equated to two septimal commas. In fact, buzzard slices the [[256/243\|Pythagorean limma]] into four, one for 64/63, two for 49/48, and three for [[28/27]].

			By finding [[harmonic]] [[5/1\|5]] twenty-one generators away, buzzard is [[extension and restriction\|extended]] to the full [[7-limit]], where it tempers out [[1728/1715]] and [[5120/5103]]. This equates the [[81/80\|syntonic comma]] with the septimal comma and turns it into a generic comma step that can be used to bridge Pythagorean intervals with both classical and septimal intervals. Buzzard then extends naturally to the [[13-limit]] by identifying the semitwelfth as [[26/15]], and identifying the comma step as the [[100/99\|ptolemisma]] (100/99, {{S\|10}}). This means [[176/175]], [[351/350]], [[540/539]], and [[676/675]] all vanish.

			Finally, it is possible to extend buzzard to the [[19-limit]], where it merges [[17/16]] and [[16/15]], tempering out [[256/255]] ({{S\|16}}), and merges [[26/15]] and [[19/11]], tempering out [[286/285]].

			Buzzard can be tuned to [[53edo]], [[58edo]], or [[111edo]]. [[Mos scale]]s of buzzard cluster strongly around [[5edo]], similar to those of [[rodan]].
