Mahler Symphony No. 7  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), though this title was not Mahler's own and he
disapproved of it.  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". The complexity of the
work's tonal scheme was analysed in terms of 'interlocking
structures' by Graham George.  In 1904, Mahler was enjoying
great international success as a conductor, but he was also, at
last, beginning to enjoy international success as a composer.
