The scale with the lowest harmonic entropy for this [[MOSScales|MOS]] pattern is [[Semaphore|semaphore]], in which two generators make a 4/3. The other interesting scale is [[Semicomma_family|orwell]], in which the generator is approximately 7/6 and three of them make an 8/5.

== Modes ==
Each mode has a "name" provided by TAMNAMS, consisting of a number (of generators up from the root present) and pipe. Modes can also be referred to using their pattern of large (L) and small (s) steps. Additionally, cellularAutomaton has proposed names based on Latin names for fingers of the hand for increased distinctiveness and memorability.
Modes of 4L 1s can be named systematically either with [[modal UDP notation]], rotational order (with 1 being the [[bright]]est mode) or the [[step pattern]].

4L 1s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 4 large steps and 1 small step, repeating every octave. Generators that produce this scale range from 240 ¢ to 300 ¢, or from 900 ¢ to 960 ¢. Scales of this form are always proper because there is only one small step. The scale with the lowest harmonic entropy for this mos pattern is semaphore, in which two generators make a 4/3. The other interesting scale is orwell, in which the generator is approximately 7/6 and three of them make an 8/5.

Names

The TAMNAMS system uses the name manual, a name that is thematically inspired by the Latin word "manus".

Modes

Modes of 4L 1s can be named systematically either with modal UDP notation, rotational order (with 1 being the brightest mode) or the step pattern.
