Mass No. 5 in A-flat major, D 678, is a mass composed by Franz Schubert, completed in 1822. There is no record of a performance during Schubert's lifetime. It is scored for soprano, alto, tenor and bass soloists, SATB choir with divisi, violin I and II, viola, flute, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, 3 trombones colla parte, timpani and basso continuo (cello, double bass and organ). It is classified as a missa solemnis.
Background
Schubert commenced composition of the mass in November 1819, completing it three years later in 1822. Various projects had competed for the composer's attention in the meantime, including his brother Ferdinand's request for a mass (D 755). Schubert wrote out the organ part in October or November 1822, and although plans were made for a performance in 1823, records of a performance in Schubert's lifetime do not exist.
This setting and the later Mass in E-flat major are regarded as Schubert's "late masses". These are distinguished from his four early masses by their "musically interpretive stance to the words"; Schubert began to take advantage of an overall maturation in his technical capabilities and knowledge of harmony, coupled with his experience in composing both sacred and secular music, to add further meaning to the standard text. Already known for consistently omitting certain passages from the text, Schubert took even greater freedoms in the late masses, adding and removing text in a bid to "deepen expression or enhance a particular aspect of meaning".
Schubert revised his original setting in 1826, producing a shorter, simplified fugue for the Cum Sancto Spiritu section of the Gloria, and changing the Osanna. In 1827, Schubert used this revision as an audition for the position of deputy kapellmeister in the Imperial Court Chapel, an ultimately unsuccessful venture. The Hofkapellmeister Joseph Eybler denied Schubert's request for a court performance of the mass, on the grounds that it was not in the Kaiser's preferred style; Eybler may have invented this excuse as he favoured the court composer Joseph Weigl, and did not wish to pay Schubert the honorarium the performance would incur.
The Schubert scholar Brian Newbould considered the late masses to be the composer's "two finest and most substantial settings", and that Schubert himself must have regarded the Mass in A-flat very highly, judging by his "extended labours" and numerous returns to the setting. In a December 1822 letter to his friend Joseph von Spaun, Schubert contemplated dedicating the mass to the Emperor or Empress, "for it has turned out well".
Mass No. 5, as well as the unfinished setting of the oratorio Lazarus (D 689), are seen as products of Schubert's reflections on life and death.
The late masses may have influenced the composition of Bruckner's Mass in F minor.
