Can anyone help me on how to do such a thing that reacts on your body without one touching it - Don't need it to play music just get the signals in..

I'm new to Arduino and code..

Thank you for your time

Just electromagnetic fields. :)

Sticking your hand near it alters the field and the wire picks it up.

Yes I know it uses the electromagnetic fields but how is the circuit made? I'm a newbie and is quite unsure how to do these kind of things...

Use a LDR (Light Dependent Resistor) hooked up to an analog input and use the code floating around for making a sound with a frequency depending on the reading of the LDR. Use your hand to allow more or less light to reach the LDR. This gives you the frequency part of an Theremin. The volume control is not that easy :-)
