backfall
English era
Definition
An English Baroque ornament: a single-note appoggiatura falling from the note above. It takes a portion of the value of the main note and resolves downward by step. Also called a plain note and shake when followed immediately by a shake.
Interpretive Guidance
Give the backfall enough weight and duration to create a brief expressive leaning before resolving. On the harpsichord the effect is produced purely through timing; on piano a slight dynamic emphasis on the ornament note helps.
