{{MOS intro}} | |||
One of the [[harmonic entropy]] minimums in this range is [[Kleismic family|Kleismic/Hanson]]. | |||
== Name == | |||
TAMNAMS formerly used the name ''kleistonic'' for the name of this scale (prefix ''klei-''). Other names include '''p-chro smitonic''' or '''smipechromic'''. | |||

=== Soft range === | |||
The soft range for tunings of 4L 7s encompasses parasoft and hyposoft tunings. This implies step ratios smaller than 2/1, meaning a generator sharper than {{nowrap|4\15 {{=}} 320{{c}}}}. | |||
This is the range associated with extensions of [[Orgone|Orgone[7]]]. The small step is recognizable as a near diatonic semitone, while the large step is in the ambiguous area of neutral seconds. | |||
Soft edos include [[15edo]] and [[26edo]]. | |||
The sizes of the generator, large step and small step of 4L 7s are as follows in various soft tunings: | |||

=== Hypohard === | |||
Hypohard tunings of 4L 7s have step ratios between 2/1 and 3/1, implying a generator sharper than {{nowrap|5\19 {{=}} 315.79{{c}}}} and flatter than {{nowrap|4\15 {{=}} 320{{c}}}}. | |||
| | This range represents one of the harmonic entropy minimums, where 6 generators make a just diatonic fifth ([[3/2]]), an octave above. This is the range associated with the eponymous Kleismic (aka [[Hanson]]) temperament and its extensions. | ||
Hypohard edos include [[15edo]], [[19edo]], and [[34edo]]. | |||
The sizes of the generator, large step and small step of 4L 7s are as follows in various hypohard tunings: | |||

=== Parahard === | |||
Parahard tunings of 4L 7s have step ratios between 3/1 and 4/1, implying a generator sharper than 6\23 = 313.04¢ and flatter than 5\19 = 315.79¢. | |||
| | |||
The minor third is at its purest here, but the resulting scales tend to approximate intervals that employ a much higher limit harmony, especially in the case of the superhard 23edo. However, the large step is recognizable as a regular diatonic whole step, approximating both 10/9 and 9/8, while the small step is a slightly sharp of a quarter tone. | |||
Parahard edos include [[19edo]], 23[[23edo|edo]], and [[42edo]]. | |||
The sizes of the generator, large step and small step of 4L 7s are as follows in various parahard tunings: | |||

=== Hyperhard=== | |||
Hyperhard tunings of 4L 7s have step ratios between 4/1 and 6/1, implying a generator sharper than 8\31 = 309.68¢ and flatter than 6\23 = 313.04¢. | |||
| | The temperament known as Myna (a pun on "minor third") resides here, as this is the range where 10 generators make a just diatonic fifth (3/2), two octaves above. | ||
These scales are stacked with simple intervals, but are melodically difficult due to the extreme step size disparity, where the small step is generally flat of a quarter tone. | |||
| | |||
| | |||
| | |||
Hyperhard edos include [[23edo]], [[31edo]], and [[27edo]]. | |||
