How does the laser harp work?

This instrument has a very interesting design and is simply "Built" with parallel laser beams only each other that can exceed two meters in height.

It works in a rather peculiar way because the musician only has to block a beam with his hand for a photodiode or photoresistor, generally connected to an electronic console, to detect it. When this happens a specific musical note is activated; in turn, the sound is reproduced with the help of a computer or synthesizer that is connected to the instrument.

There are several versions and designs even when one of them uses MIDI technology, which is capable of transmitting up to sixteen information channels that can be connected in different devices but that interact and communicate with each other. The latter was created by Philippe Guerre. Others prefer the model designed by Maurizio Carelli that uses two types of colors, red and green.

How dangerous is it to use the laser harp?
