Demonstration of how to encode notes in a chord which
do not all have the same duration. This example contains
an arpeggiated chord containing two quarter notes and one
half note. The logical duration of the chord is a half-note.
This example is taken from Mozart's piano sonata no. 6 in
D major (K1 284 / K6 205b), mvmt. 3,
variation 4 (Alte Mozart-Ausgabe).
