Specifically In music: A succession of tones, whether pleasing or not.

The underlying relationship may be variously established: by any particular rhythmic arrangement, as in some popular dance-tunes; by the intervals of a single chord, as in arpeggio phrases; by a diatonic order, as in scale passages; by the harmonic connections between successive chords of which the melody in question forms one of the voice-parts, as in simple choral writing; and by innumerable modifications and combinations of these and similar principles.
