'''3L 4s''' is the [[MOS scale]] built from a generator that falls between 1\3 (one degree of [[3edo]] – 400 cents) and 2\7 (two degrees of [[7edo]] – 343 cents). | '''3L 4s''' is the [[MOS scale]] built from a generator that falls between 1\3 (one degree of [[3edo]] – 400 cents) and 2\7 (two degrees of [[7edo]] – 343 cents). | ||

The notation used in this article is sLsLsLs = JKLMNOPJ unless specified otherwise. We denote raising and lowering by a chroma (L − s) by & "amp" and @ "at". (Mnemonics: & "and" means additional pitch. @ "at" rhymes with "flat".) | The notation used in this article is sLsLsLs = JKLMNOPJ unless specified otherwise.

One system for naming MOSes, TAMNAMS (used by this article), uses the name '''mosh''' for this pattern. This is taken from an older [[MOS naming]] scheme by Graham Breed. | One system for naming MOSes, TAMNAMS (used by this article), uses the name '''mosh''' for this pattern.
