In how many musical contexts can the theremin be used for?

here you go

Explanation:

The theremin is a monophonic instrument; which is to say, it can only produce one pitch at a time. It has about a five-and-a-half octave range. Its low range can sound like a cello or string bass, mid range to upper range can be vocal-like and the top end is brilliant and piercing.

the correct answer would be "the amiens cathedral"
