The Phantasmic One-man Band

As an action, you can summon two semi-translucent hands that can take up any musical instrument within range and begin to play it. You must be skilled in the musical instrument and the quality of play is based on a performance check using your modifier. The hands are immune to damage and cant be directly stopped from playing unless the instrument is destroyed. 

This spell's ability to summon more hands to play more musical instruments increases by 1when you reach 5th level (2), 11th level (3), and 17th level (4).
