is a saxophone a woodwind or brass instrument
Saxophone The saxophone (also referred to as the sax) is a family of woodwind instruments. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet.[2] Like the clarinet, saxophones have holes in the instrument which the player closes using a system of key mechanisms. When the player presses a key, a pad either covers a hole or lifts off a hole, lowering or raising the pitch, respectively.
Orchestra The typical symphony orchestra consists of four groups of related musical instruments called the woodwinds, brass, percussion, and strings (violin, viola, cello and double bass). Other instruments such as the piano and celesta may sometimes be grouped into a fifth section such as a keyboard section or may stand alone, as may the concert harp and electric and electronic instruments. The orchestra, depending on the size, contains almost all of the standard instruments in each group.
