Rate this CT I came up with

Name: Rhythmic Resonance

This technique allows the user to use sound to generate vibrations in an opponent's body, as well as pick up on the "rhythm" of their opponent's attacks. An opponent's rhythm becomes harder to pick up on depending on how much more total cursed energy they have.

This technique has two modes that the user switches between by tapping their heart:

Staccato: Makes vibrations more intense, but makes it harder to pick up on enemy rhythms.

Legato: The inverse of Staccato – makes it easier to pick up on a rhythm, but attack power suffers.

Maximum Technique: Crescendo. After striking an enemy enough times, the technique user can detonate the vibrations built up inside the opponent's body, dealing heavy damage.

Domain: Symphony of War

Manifests a concert hall with musical notes floating around.

Sure-hit effect: Allows the technique user to instantly pick up on the opponent's rhythm regardless of their cursed energy volume, and assigns the opponent a "rhythm" that's completely different from the one they had before, making their movements feel awkward so they second-guess each decision.

Let me know what you think, what changes you would make, and what grade a sorcerer could achieve using this technique.
