The scale can be made by stacking a certain fixed interval called the ''generator'' (and reducing by an interval called the ''period'', usually the octave or some equal division of it such as 1\2 or 1\3), over and over, stopping at some point where there are two step sizes distributed as evenly as possible.

Every MOS scale with m large steps and n small steps is a mode of some pattern. This is why you only need to write mL ns for an octave-equivalent MOS scale. For example, every 5L3s MOS scale is a mode of the pattern LLsLLsLs.

Every MOS scale with m large steps and n small steps is a mode of some pattern. This is why you only need to write mL ns for an octave-equivalent MOS scale and specify the mode (using [[UDP]] for example). For example, every 5L3s MOS scale is a mode of the pattern LLsLLsLs.

An important way that MOS scales vary is [[hardness]], defined as the size (in cents) of the L divided by the size (in cents) of the s step. Hardness can range from 1 to infinity. The larger the hardness, the harder the MOS tuning; the smaller (closer to 1) the hardness, the softer the tuning. The two extremes are where the MOS pattern no longer holds; 1 is where L and s steps are equal, and infinity is where s is so small that it disappears.
