A world where music becomes magic
Every living being is born with a unique sound, a **"Wavelength."** When a person performs their wavelength through instruments or voice, they can interfere with reality. From notes that ignite fire and harmonies that heal wounds to dissonances that warp space itself. And on very rare occasions, when the sounds of multiple people align perfectly, a phenomenon impossible with ordinary magic occurs: **"Resonance."** The world's premier music magic school that researches this resonance and trains performers is Cadenza Academy. - Immediately after admission, students are assigned to dormitories and undergo a Selection Ceremony to choose a department suited to their aptitude. & One year ago, when the score titled "Diciannove" first appeared and was performed, it caused massive destruction. That score is currently sealed in the Cadenza Academy archives. Many covet the score for its power. (Fortunately, there were no casualties at the time.) 🎼 Departments - Each department has its own top student! 1. Strings Department Violin, Viola, Cello, Harp, etc. Characteristics: Specializes in precision magic. A single stroke of a string can create a shield or sever an opponent's magic. 2. Woodwinds & Brass Department Flute, Clarinet, Oboe, Trumpet, etc. Characteristics: Wide-range and powerful magic. Fires sound itself like bullets or manipulates the wind. 3. Percussion Department Drums, Timpani, Xylophone, etc. Characteristics: Physical enhancement and destructive power. Physical abilities increase as the tempo quickens. 4. Vocal Department Uses the human voice. Characteristics: The most dangerous department. The voice can influence another person's wavelength far more directly than an instrument. 5. Composition Department Creates pieces instead of performing them directly. Composed scores function identically to actual magic formulas. A great composer can activate massive magic with a single score even without a performer. — 「The Piece」 If mages have spells, Sound Casters have pieces. A piece consists of three elements: Melody — Will Harmony — Relationship Rhythm — Time Therefore, there is a limit to a piece that can be completed alone. The more people perform together, the more their wavelengths connect, creating unexpected new magic. That is why ensemble performance is the most important thing at this school. The problem is, People who dislike each other can never achieve a perfect ensemble. ☆☆ Festival ☆☆ - At the end of the school year, applicants perform their own original compositions or ensembles on the auditorium stage.
