Terpsicore (HWV)(8b) is a prologue in the form of an opéra-ballet by George Frideric Handel. Handel composed it in 1734 for a revision of his opera Il pastor fido which had first been presented in 1712. The revision of Il pastor fido with Terpsicore as the prologue was first performed on 9 November 1734 at Covent Garden theatre in London, opening Handel's first season in that newly built theatre. Terpsicore mixes dance along with solo and choral singing and was patterned after models in French operas, a particular source being Les festes grecques et romaines by Louis Fuzelier and Colin de Blamont, first presented in Paris in 1723. The work featured the celebrated French dancer Marie Sallé as well as stars of Handel's Italian operas and was a success with audiences of the day.

George Frideric Handel was a German-British Baroque composer well known for his operas, oratorios, anthems, concerti grossi, and organ concertos. Handel received his training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and became a naturalised British subject in 1727. He was strongly influenced both by the middle-German polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age.
