Ornamentation

- Trills.
- Appoggiaturas (a grace note that takes time away from the note following it).
- Acciaccaturas (a grace note that is played as quickly as possible).

Ornamentation cont.

- Mordents (alternation between the notes surrounding the note that is written).
- Scalic runs (moving up or down the scale).
- These all feature within the set work.

Baroque period

- Sequences (b.137).
- Pedal notes (b.90-95).
- Stretto (where the subject is repeated on top of itself) (b.64-68).
- Cadences (musical punctuation).
