Echoing Note

You sing a sharp, resonant tone toward one creature you can see. Make a ranged spell attack. On a hit, the target takes 1d8 thunder damage and must succeed on a Constitution saving throw or have disadvantage on its next attack roll as the echo distracts it.

Damage increases to 2d8 at 5th level, 3d8 at 11th, 4d8 at 17th. The disadvantage effect remains unchanged.
