Method and apparatus for controlling musical sounds by player's foot movements

A method of controlling musical sounds, the method comprising the steps of:

• placing a piezoelectric sensor device between a foot of a user and an inner sole top surface of a footwear;
• applying a pressure force by the foot of the user to the piezoelectric sensor device to generate control signal for controlling musical sounds;
• mounting the piezoelectric sensor device on an insole-shaped member that fits inside the footwear;
• inserting the insole-shaped member inside the footwear to place the piezoelectric sensor device on the inner sole top surface of the footwear;
• dividing the piezoelectric sensor device into a front sensor section and a rear sensor section;
• and
• slidably coupling the front sensor section section and the rear sensor section.
