Cavatina

You create a minor magical flair that performers use to enhance their shows. You create one of the following magical effects within range:

• Your voice or a musical instrument you touch increases in volume up to three times as loud as normal for 1 hour.
• You create an instantaneous sound that originates from a point of your choice within range, such as a drum sting, laughter or sigh by an audience, or the sound of applause.
• You change the color of a source of light within range. The amount of light produced is unchanged.
• You create an instantaneous, harmless visual effect, such as a shower of fireworks, floating musical notes, or a spotlight.

If you cast this spell multiple times, you can have up to three of its non-instantaneous effects active at a time, and you can dismiss such an effect as an action. You can cast this spell while playing a musical instrument, without stopping.
