Eighteenth-Century Trill 1

A trill is an ornament performed by moving rapidly between the main note and the note above it. It is normally notated in music by placing a “tr” in superscript above the note that is trilled. In the example from the first movement of Count Ferdinand Waldstein’s Sinfonie in D, the trill is played by the oboe and first violin parts as an ending to the reprise to the second theme. Trills were often used to exaggerate the resolution of a phrase in the eighteenth century.
