Gustav Mahler's Seventh Symphony was written in 1904–05, with repeated revisions to the scoring. It is sometimes referred to by the title Song of the Night (German: Lied der Nacht), which Mahler never knew and certainly would never have sanctioned Although the symphony is often described as being in the key of E minor, its tonal scheme is more complicated. The symphony's first movement moves from B minor (introduction) to E minor, and the work ends with a Rondo-Finale in C major.
