Heiligenstadt no Uta

Lied is an orphan living alone in the magical town of Shall, accompanied by her talking cockatiel Soprano—who can speak because that is the kind of place Shall is. She plays piano for her old orphanage, though she would be the first to admit she is not very good at it. When five young men arrive in town, each carrying the Falga power of a legendary classical pianist, and the Forgotten Apostle begins stealing all sound from Shall because of a "dark noise" emanating from performers, Lied joins the magical academy to restore music and drive the Apostle out.
