Sul-sul! I'm back with another music related mod, which adds Violin/Piano duets to the game. Once your Sims reach level 5 or higher on Violin or Piano, they will be able to choose one of 5 duets to play.
Once you choose a song, you'll be prompted to choose an instrument and your duet partner. A few quirks: your violin must not be in the Sim's inventory to access the Play Duet interaction, and your Sim must not be sitting at the piano for it to appear.
Note: This mod requires the XML Injector. If you do not already have a copy in your game, you can download it here.
Hope you enjoy!
