The first set of mode nicknames was coined by [[Andrew Heathwaite]]. The other set was coined by [[User:CellularAutomaton|CellularAutomaton]] and follows the diatonic modes' naming convention by using ancient Greek toponyms that sound similar to Heathwaite's names. The third shows which modes are a mixture of which diatonic modes, as discussed in [[#Theory]]. | |||

Mosh can be thought of as a midpoint between two diatonic scales which are two cyclic orders away from each other. For example, sLsLsLs is the midpoint between the Ionian (major, LLsLLLs) and Phrygian (sLLLsLL) modes. You can prove this by simple addition: | |||
<pre> | |||
2 2 1 2 2 2 1 (LLsLLLs) | |||
+ 1 2 2 2 1 2 2 (sLLLsLL) | |||
= 3 4 3 4 3 4 3 (sLsLsLs) | |||
</pre> | |||
