A pull-off is a stringed instrument technique performed by plucking a string by "pulling" the string off the fingerboard with one of the fingers being used to fret the note.  Pull-offs are performed on both fretted instruments (e.g., electric guitar) and unfretted instruments (e.g., violin). They are used to sound grace notes, in part because since the string is not picked or bowed again to produce the sound of the second note, the transition from one to the other sounds gentler and less percussive.

The trill (or shake, as it was known from the 16th until the 19th century) is a musical ornament consisting of a rapid alternation between two adjacent notes, usually a semitone or tone apart, which can be identified with the context of the trill.

Boudica alternative spelling: Boudicca, also known as Boadicea and known in (d. AD 60 or 61) was queen of the British Iceni tribe who led an uprising against the occupying forces of the Roman Empire.
