Agrell’s sinfonias balance on a threshold in genre history, as the three-movement symphony with an opening sonata form Allegro gradually overtook different suite forms as the central means of instrumental music for larger ensembles. Some of the works prefigure the four-movement symphony that arose fully only after the death of Agrell (for example those composed by Joseph Haydn in the 1760s). The chronology of the sinfonias is difficult to ascertain, but the pioneering work of Agrell scholar Jeannette Morgenroth Sheerin (1952–2020) at the Notre Dame University, Indiana, has laid solid foundations for all future research into Agrell’s instrumental music. Six of the sinfonias are performed by Drottningholms Barockensemble on this album.
