I want to know the answer to the following question:
What is an example of a lesser-known instrument taught at Eton?
All the background I'm provided with is that "The current "Precentor" (Head of Music) is Tim Johnson, and the School boasts eight organs and an entire building for music (performance spaces include the School Hall, the Farrer Theatre and two halls dedicated to music, the Parry Hall and the Concert Hall).". Is that enough to answer the question?
Answer: no
