SX50 Low Light Tips?

I have been asked to take some photos of my wife's sound healing group where she plays Native American flutes.

I know from experience that my SX50 is fantastic outside in the daylight with wildlife, but it is not a great indoors, low-light camera.

I can't use flash either as it would affect the sound healing experience.

Any tips? Any ways I can coax the best possible pictures out of this camera?

Tripod and manual exposure for lighting situation. If dark, you may need a higher than desirable iso... Shoot in raw as well for extra pp options..

Shoot manual, widest apertures you can use and highest ISO you can use.

I'd try and aim for a 1/100-1/200 exposure.

Also shoot in raw in case the stage lighting trips you up.

Thanks Alex and AP.

I had planned on using a tripod and shooting manually and will be shooting in RAW. The tip for 1/100-1/200 is good. What is the max ISO I should try for?
