For example, the hexachord beginning on C and rising to A, named hexachordum naturale, has its only semitone between the notes E and F, and stops short of the note B or B ♭.

The fact that τόνος itself has at least four distinct meanings in Greek theory of music contributes to the uncertainty of the exact meaning and derivation of διατονικός, even among ancient writers: τόνος may refer to a pitch, an interval, a "key" or register of the voice, or a mode.
The semitone appeared in the music theory of Greek antiquity as part of a diatonic or chromatic tetrachord, and it has always had a place in the diatonic scales of Western music since. The various modal scales of medieval music theory were all based upon this diatonic pattern of tones and semitones.
The word limma or leimma (from Greek: λείμμα, leimma; meaning "remnant") can refer to several different musical intervals, and one form of breath-mark to indicate spacing within lyrics; their only common property is that all are very small either in pitch difference or in time.
The most important of all the consonant species was the octave species, because "from the species of the consonance of the diapason arise what are called modes". [5] The basis of the octave species was the smaller category of species of the perfect fourth, or diatessaron; when filled in with two intermediary notes, the resulting four notes and three consecutive intervals constitute a ...

A ditone (or major third) is an interval formed by two major tones. In Pythagorean tuning, a major tone has a size of about ...

Ten different notes in all are used in this first verse. The fourth note from the bottom, written Μ (Mu in the Greek alphabet, or the note C in the conventional modern transcription) is the so-called mesē, or central note, to which the music most often returns. [10] Music with this mese was said to be in the (Greek) Phrygian mode (modern ...
