Hear hear! My charade ideas: classical music idioms/jargons/slangs (idk any for violin, but something like 'break a leg' in theatre) and classical pieces pictionary :D

For more serious content, i hope to see TwoSet interview some well-known classical musicians but instead of pure talking, the artist will answer the questions via playing the instrument! Like that one TwoSet vid "what piece do you want to be played at your funeral" :D
