taken overall, the enharmonic _lichanoi_ are the lowest, the chromatic next, and the diatonic the highest.

The total range in which _lichanos_ moves is a tone, since it does not stand at less than the interval of a tone from _mese_, nor at a greater interval than a ditone.

It appears that the highest _lichanos_ is that which lies at a tone from _mese_, and creates the diatonic genus; and the lowest is that at a ditone from _mese_, which belongs to the enharmonic. Hence it is clear that the range of _lichanos_ is a tone.
