5In the centre none are to be placed, because no other sound in the chromatic genus can be in consonance therewith. In the upper division and range of the cavities, the vases on the extremities are constructed to produce the tones of the diatonic hyperbolæon: in the next cavities, those of the diatonic diezeugmenon, a fourth: in the third, of the diatonic synèmmenon, a fourth: in the fourth, of the diatonic meson, a fourth: in the fifth, of the diatonic hypaton, a fourth: in the sixth, proslambanomenos, a fourth: in the centre, mesè, between which and proslambanomenos is an octave, and a fifth between it and the diatonic hypaton.
5No vessel is to be placed in the middle, for the reason that there is no other note in the chromatic system that forms a natural concord of sound.
In the highest division and range of niches, place at the extreme ends vessels fashioned so as to give the note of the diatonic hyperbolaeon; next, the diatonic diezeugmenon, a fourth below; third, the diatonic synhemmenon; fourth, the diatonic meson, a fourth below; fifth, the diatonic hypaton, a fourth below; sixth, the proslambanomenos, a fourth below; in the middle, the note mese, for this is both the octave to proslambanomenos, and the concord of the fifth to the diatonic hypaton.
