Nupelog is a 7-note generator-offset scale with step pattern 2L 2M 3s (sMLssML), equivalent to the 2L 5s MOS with two of the small steps made larger. It occupies a broad triangle on the chart of MV3 scales, whose vertices are generators [0\1,1\2] degenerate to 2edo, [2\7,4\7] degenerate to 7edo, and [1\2,1\2] again degenerate to 2edo.
Unanswered Questions:
*Is it chiral?
*What are the just intervals strongly implied by certain tunings?
"Nupelog" is a name given to this region by Kaiveran, reflecting both the pelogic family of temperaments, and the fact that several measured tunings of the Indonesian pelog have a very similar step pattern.
Intervals
The following is a table of nupelog intervals and their abstract sizes in terms of L, M and s. Given concrete sizes of L, M and s in edo steps or cents, you can compute the concrete size of any interval in nupelog using the following expressions.
| Interval class | Sizes | ??? | ??? | ??? |
|---|---|---|---|---|
| 1-step | ||||
| 2-step | ||||
| 3-step | ||||
| 4-step | ||||
| 5-step | ||||
| 6-step |
Since nupelog is heptatonic, there is little issue with calling the "perfect 7-step" the octave, as in diatonic music.
