A prototypical 5L 2s 5|1 (Ionian) scale would be spelled C, D, E, F, G, A, B, (C).

Simple otonal chords can be plucked out of the harmonic segment 1:2:3:4:6:8:9:12:16:18:24:27:32:36:48:54:64:72:81:96:108:128:... e.g. 6:8:9 is a sus4 chord.

The 2.√(3/2) part can be notated using [[neutral chain-of-fifths notation]]. This introduces a neutral interval quality between major and minor, semisharps (a.k.a. demisharps) etc.

Simple hemipyth chords can be plucked out of the square root of the Pythagorean segment 1:√2:√3:2:√6:√8:3:√12:4:√18:√24:√27:√32:6:√48:√54:8:√72:9:√96:√108:√128:... e.g. 2:√6:3 is a neutral chord where spicy tension can be added by including the semioctave for 2:√6:√8:3 with no increase in complexity as far as the generator of the subgroup is concerned.
