In his desire for music, man was soon confronted with the limitations of the only instrument that nature gave him: his body and his voice. In search of new sounds, new tones and new ways of expression, he began to build tools whose only purpose was to produce sounds. Thus were born thousands of instruments, all using different kinds of techniques and materials, from percussion made of wood or skin to wind instruments made from copper; bowed, plucked or struck strings to electronic instruments.
