# Orchestra

An orchestra (; OR-ki-strə) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: String instruments, such as the violin, viola, cello, and double bass Woodwinds, such as the flute, oboe, clarinet, bassoon, and occasional saxophone Brass instruments, such as the French horn (commonly known as the "horn"), trumpet, trombone, cornet, and tuba, and sometimes euphonium Percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, tam-tam and mallet percussion instruments Other instruments such as the piano, harpsichord, pipe organ, and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments, and guitars. A full-size Western orchestra may sometimes be called a symphony orchestra or philharmonic orchestra (from Greek phil-, "loving", and "harmony").
