How to make a theremin
Learn the essential components of the theremin.
A theremin is basically a box with two antennas, one of which controls the pitch of the instrument, the other of which controls the volume. These antennas create electromagnetic fields which are " played " by manipulating them with the hands.

Possible answers:
1). They are tuned and manipulated using the head and antenna of your instrument. The operation of this type of theremin is complicated.;
2). The theremin usually goes in a box, so this is where the crankoperators come in handy. The theremin is designed to perform various tasks on your instrument, such as transferring notes from string to a circle.;
3). Coils of tight-pack wire act as oscillators, producing signals fed into the antennae. While it may seem like spooky magic, the fields are created by relatively straightforward circuitry.;
4). Depending on the instrument size and equipment, each would produce a different pitch. For a theremin you may want to order a set of around.;
