Ask about the parameters and skills when shooting dancing with SLR.

There are no parameters worth mentioning. It all depends on the scene and the effect you want to shoot. If you want to say that you don't want to paste, then increase the shutter speed (by increasing the aperture and ISO). If you want stage lighting, try to use close-ups (personal experience, try to make the bright area of the stage full of pictures), or shoot the desired effect with M-files according to the metering situation at that time.
