'''Flattone''' is an alternative extension of meantone, which 7/4 is represented by a diminished seventh rather than augmented sixth. The fifth interval is adjusted narrower, nine of which give 8/7 and thirteen of which give 10/7 with octave reduction. Alternatively, stacking three minor thirds results in a diminished seventh that is close to 7/4. | '''Flattone''' is an alternative extension of meantone, which 7/4 is represented by a diminished seventh rather than augmented sixth.

'''Dominant''' is an alternative extension of meantone, which 7/4 is represented by a minor seventh rather than augmented sixth. This results equating 6/5 with 7/6 and 5/4 with 9/7, or tempering out [[36/35]] (septimal quarter tone) and [[64/63]] (Archytas comma). | '''Dominant''' is an alternative extension of meantone, which 7/4 is represented by a minor seventh rather than augmented sixth.
