Carnival of the Animals
There are 14 short movements, with a short introduction. Saint-Saëns arranged it for an orchestra consisting of flute doubling piccolo, clarinet (B flat and C), two pianos, glass harmonica, xylophone, two violins, viola, cello and double bass. Today it is often performed with a full orchestra of strings, and with a glockenspiel instead of a glass harmonica, which is an unusual instrument.
