Baroque versus Renaissance
There exist two families of recorders, the Baroque and the Renaissance. The Baroque recorder is the standard model that most people are aware of. It is a more refined instrument with a clearer sound and a larger range. The Renaissance instruments are earthier in tone and generally only have a range of an octave and a half. It is possible for a bandestrator to specify the use of either Baroque or Renaissance, but chances are that it will just be played upon the Baroque anyway.
