Interval lattice
Notation
Marvel can be notated the same as 5-limit just intonation since they share the same lattice structure.
One way to do this is to take the conventional circle-of-fifths notation with an additional module of accidentals for the 81/80 comma. In this system, 5/4 is a major third, 7/4 an augmented sixth, and 11/8 a double diminished 5th.
| Ratio | Nominal | Example |
|---|---|---|
| 3/2 | Perfect 5th | C-G |
| 5/4 | Down major 3rd | C-vE |
| 7/4 | Double down augmented 6th | C-vvA# |
| 11/8 | Triple up double diminished 5th | C-^3Gbb |
