Sims 4 music/band expansion

I was sitting here listening to my husband play the sims and his sim was playing the keyboard and suddenly I realized that all of the sims games are very limited in their instruments. They've covered the basics, guitar, piano, drums, violin, etc. but never anything beyond that. It would be nice for people who are musicians (both rock and classical) to have more of a variety such as trumpets, clarinets, flutes, and saxophones. Those are just to name a few. One could combine them to make a band like you could in 2 and 3. Using the Get Together clubs you could even have band clubs or something. I don't know, I'm not the creative people here. I just want more instruments/musical stuff.
