Symphony no. 7 in E minor “Lied der Nacht”

The Symphony No. 7 by Gustav Mahler is a symphony in five movements composed in 1904–05, sometimes referred to by the title Song of the Night (German: Lied der Nacht), which was not the composer's own designation. 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. Thus, as Dika Newlin has pointed out, "in this symphony Mahler returns to the ideal of 'progressive tonality' which he had abandoned in the Sixth".
