An early music ensemble is a musical ensemble that specializes in performing early music of the European classical tradition from the Baroque era and earlier – broadly, music produced before about 1750. Most, but not all, of these groups are advocates of historically informed performance, and attempt to re-create the music as it might have sounded at the time it was written, using period instruments and modifying playing techniques according to the most recent scholarly research into music of the time.
