To be honest, it's a good idea that you can think of wedding-style live music. There are two famous wedding marches, but they are all full of voices. Violin is just a high-pitched instrument, and the two really don't have much effect. It's ugly and thin, not as good as a piano, but renting grand piano is at least 2000-3000, which is still the smallest. So, find a recording, or you can play the recording and let the violin play. After all, people with 100 yuan have to come out once. As a small city, I think it is too cheap to find 100 yuan in Beijing. If it goes out of tune, it will spoil the atmosphere.

Otherwise, it needs at least four people, two notes, 1 viola, 1 cello and string quartet.
