Musical instruments are divided into various groups known as instrument families. The four main families are woodwinds, brass, percussion, and strings. Woodwind instruments are not -- as one might imagine -- made of wood, but they do all have many tone holes that are covered by either keys or fingers. Brass instruments are long tubes bent in various shapes that are made of a type of metal alloy called brass (though they may be lacquered or plated with silver). The percussion family includes a variety of pitched and non-pitched instruments that are typically struck by a stick or mallet to produce a sound. String instruments produce sound by means of a string that is stretched across the instrument, which the player either bows or plucks.
