Arpeggiation
The arpeggiation is perhaps the easiest diminution to spot. It prolongs a harmonic unit by arpeggiating (making into an arpeggio) the notes of the triad.
Here is an arpeggiation of a root position C major triad. Arpeggiations may ascend or descend but they cannot do both. They can arpeggiate any inversion of a triad, but must do so without missing any notes out (C - G - C would not be an arpeggiation):
Here is an arpeggiation of a first inversion C major triad in the bass:
Note the way that Schenkerian analyses are notated: there are no stems on the noteheads and a slur spans the linear unit or diminution in question. Stems, beams and minim noteheads are used at other stages of an analysis (see Notation Guide)
