Arpeggiation
A single chord is often elaborated by playing the notes separately, as an arpeggio of some sort. When a
chord is spread through time in this way a reduction will represent the chord as if all the notes were played
simultaneously. In the previous chapter the Alberti bass pattern was interpreted in this way. In a similar
way this bar from Bach's first prelude can be interpreted as a single chord.
Bach, Well Tempered Clavier I, Prelude No 1
The opening of Beethoven's first piano sonata can be treating the same way.
Beethoven, Sonata, Op 2, No 1, I
