An orchestra 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 horn, trumpet, trombone, cornet, euphonium, and tuba
• Percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, tam-tam and mallet percussion instruments
