Dissonance

Whether playing an instrument or singing, you perform a series of presto, fortissimo tritones that stack, sustain and reverberate forming a jagged, purple, sound wave that streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 psychic damage.

The spell creates more than one wave when you reach higher levels: two waves at 5th level, three waves at 11th level, and four waves at 17th level. You can direct the waves at the same target or at different ones. Make a separate attack roll for each beam.
