A Delay is a technique of realization which always implies the sequence of two chords (*). This occurs when a real note from the first chord is prolonged into the next chord, momentarily becoming an accidental note by taking the place of a real chord tone, before resolving to the note it replaced. Thus, for a note of a chord to be delayed, its necessary for the note which causes the delay must be prepared.
Examples.
Delays are divided into two species:
- Suspensions
- Irregular Delays, which will simply be called delays.
