4 years ago I like this, but I wonder if it should be against their Insight instead.
It also seems like making a Deception check might be more appropriate. While it's certainly important to be able to keep up the performance, you're primarily trying to see if you can slip the spell past your audience, not if you can continue to play well while doing so. (Yes, playing poorly might tip the audience off, but avoiding playing in a suspicious way sounds more like Deception territory to me.)

A suggestion for a deceit-based performance:
Melodious Spell Prerequisites: Deceit theme You cunningly weave your spellcasting into your performance. If the next action you take is to cast a spell, attempt a Performance check against all observers’ passive perceptions. If your Performance check is successful against an observer’s passive perception, that observer doesn’t notice that you are casting a spell, even though normally spells have sensory manifestations that would make spellcasting obvious to those around you, and verbal, somatic, and material components are extremely overt. You hide all of these as part of an ordinary performance.
