Tremblement
A tremblement is a French Baroque trill: begin on the upper neighbour on the beat, then alternate with the written note. Its speed, length, preparation and ending vary by composer, instrument and ornament table, so a source-specific table overrides a generic expansion.
The sources do not fully agree about this sign. The explanation above says where they part company.
- Ornaments and grace notes
- Above the note
- A wave or squiggle
Do not confuse it with
A modern trill may begin on the written note; a French tremblement normally begins on the upper neighbour.
