Five Star Gift Ideas

That's an interesting hobby! Here are some gift ideas I came up with based on your friend's love for the theremin:

1. Theremin Kit: If your friend enjoys tinkering with electronics, you can gift him/her a theremin kit. It includes all the parts required to build the instrument. This will help your friend explore the inner workings of the theremin and also provide satisfaction when they finish building it.

2. Sheet Music: Your friend may be interested in learning new pieces to play on the theremin. You could get her/him sheets of music for well-known tunes or pieces. Be sure to verify that the sheet music is compatible with the theremin.

3. Audio Amplifier: Theremins require some degree of amplification to produce sound. Provide a good gift by gifting your friend an audio amplifier to boost the sound of their theremin.

4. Theremin Lessons: If your friend is new to theremin and looking to improve his/her skills, you could offer to pay for some theremin lessons. They will surely appreciate that something sort of invaluable!

5. Customized Theremin: Lastly, consider buying customized theremin with their favorite colors or design. This will make the gift very personalized and tailored to their taste. Furthermore, it is something they will be able to use and cherish for years to come.

Or you can get her/him a star map with the date when she/he was born.
