Based on comments on a fellow video-game-music-playing pianist, Taioo, piano sheet music for the Turret Opera is in high demand. So far, only the Choral / SATB version was available, which I arranged yesterday. Now there’s a piano version!
This is the as-of-now untitled operatic song at the end of the game. Due to lack of official word from Valve, it is referred to as The Fat Lady SingsTurret Opera or O Cara Mia, Addio. It was composed by Valve’s awesome in-house composer Mike Morasky. Lyrics by Ellen McLain.
