The 3L 4s MOS has a step pattern of LssLsLs, where L is a major second and s is a neutral second. We borrow note names from [[5L 2s]] (diatonic) as C, D, E, F, G, A, B. We use sharp (typed as #) and flat (typed as b) to denote an increment and decrement by {{nowrap|L-s}}, or a quarter tone. A table of intervals of this scale in 24edo is below.

In diatonic, chords are built by Root-3rd-5th. We can try to use the same logic here. This gives us neutral chords on C, E, F, G, and A, a 0¢-300¢-650¢ chord on D, and a 0¢-350¢-650¢ chord on B. This construction, however, is flawed, as none of these chords can be written with particularly simple ratios, and therefore these chords aren't very consonant. This scale is in the [[2.3.11 subgroup]], with the fundamental otonal consonance being [[8:9:11:12]] (or one of its different voicings), which in 24edo is 0-200-550-700 cents. A different construction, Root-2nd-4th-5th, is now needed. The utonal inverse of 8:9:11:12 is 1/(8:9:11:12) [[66:72:88:99]], or 0-150-500-700 cents in 24edo. The otonal 8:9:11:12 chord occurs on F and A, and the utonal 1/(8:9:11:12) chord occurs on E and G. Neither chord occurs on C, B, or D, with a 0¢-200¢-500¢-700¢ cent chord on C, and a 0¢-150¢-500¢-650¢ chord on B and D.
