Music has been a part of every culture for many thousands of years and making music has long been considered an art form. Through the centuries, music has served many purposes, from primitive rituals to lavish court entertainment, ancient religious servcies to modern secular music. The development of musical instruments is a fascinating story: from the earliest music-making devices right through to the varied and sophisticated instruments being made and played today. Instrument-making is a highly skilled craft and pieces are often beautiful creations, works of art in themselves. Today, many early instruments are valued collectors' items.
