WA pit orchestra is a type of orchestra that accompanies performers in musicals, operas, ballets, and other shows involving music. The terms was also used for orchestras accompanying silent movies when more than a piano was used. In performances of operas and ballets, the pit orchestra is typically similar in size to a symphony orchestra, though it may contain smaller string and brass sections, depending upon the piece. Such orchestras may vary in size from approximately 30 musicians to as many as 90–100 musicians. However, because of financial, space, and volume concerns, the musical theatre pit orchestra in the 2000s is considerably smaller.
WThe conductorless orchestra, sometimes referred to as a self-conducted orchestra or unconducted orchestra, is an instrumental ensemble that functions as an orchestra but is not led or directed by a conductor. Most conductorless orchestras are smaller in size, and generally perform chamber orchestra repertoire. Several conductorless orchestras are made up of only strings and focus primarily on string orchestra repertoire. Conductorless orchestras generally come from the classical music tradition and perform standard repertoire, but many conductorless orchestras promote or specialise in contemporary classical music repertoire. Many contemporary classical music ensembles also regularly perform without a conductor.
