Dragonsong by Anne McCarthy
"Petiron had left more behind than his body. He'd left her every song he'd ever known, every lay, every ballad, saga, every fingering, chord and strum, every rhythm. There wasn't any way a stringed instrument couuld be played that she didn't know, nor any cadence on the drums at which she wasn't time-perfect. She could whistle double-trills as well as any wherry with her tongue or on the reeds."
