While instrumentation of the symphony cannot be defined precisely, owing to the incompleteness of the orchestral draft, the short score has occasional indications of instrumentation, and some of the orchestration may be surmised from the three movements of the orchestral draft. The unsettled frame of Mahler's mind found expression in the despairing comments (many addressed to Alma) on the manuscript of the Tenth, and must have influenced its composition: on the final page of the final movement, Mahler wrote, "für dich leben! für dich sterben!" (To live for you! To die for you!) and the exclamation "Almschi!" (his pet name for Alma) underneath the last soaring phrase. Mahler sought counseling from Sigmund Freud, and dedicated the Eighth Symphony to Alma on the verge of its successful première in Munich in a desperate attempt to repair the breach. Mahler was at the height of his compositional powers, but his personal life was in complete disarray, most recently compounded by the revelation that his young wife, Alma, had had an affair with the architect Walter Gropius. The circumstances surrounding the composition of the Tenth were highly unusual. He had got as far as orchestrating the first two movements and the opening 30 bars of the third movement when he had to put the work aside to make final revisions to the Ninth Symphony. Mahler then started on an orchestral draft of the symphony, which begins to bear some signs of haste after the halfway point of the first movement. The fourth movement was also relocated many times. The designations of some movements were altered as work progressed: for example, the second movement was initially envisaged as a finale. The parts in short score were usually in four staves. Langsam, schwer: 400 bars drafted in short score : about 579 bars drafted in short score.Allegro moderato: 170 bars drafted in short score, the first 30 of which were also drafted in orchestral score Scherzo: 522 bars drafted in orchestral and short score.Andante– Adagio: 275 bars drafted in orchestral and short score.In the form in which Mahler left it, the symphony has five movements:

Mahler's drafts and sketches for the Tenth Symphony comprise 72 pages of full score, 50 pages of continuous short score draft (two of which are missing), and a further 44 pages of preliminary drafts, sketches, and inserts. He did not complete the orchestral draft before his May 1911 death at the age of 50 from a streptococcal infection of the blood.

Mahler started work on his tenth symphony in July 1910 in Toblach, and ended his efforts in September.
