The Asrael Symphony for large orchestra in C minor (Czech: „Asrael“, Symfonie pro velký orchestr C moll), Op. 27 (1905–1906), is a Czech symphony composed by Josef Suk. Suk wrote the work in memory of his father-in-law and teacher, Antonín Dvořák (died 1904), and his wife (Dvořák's daughter) Otilie Suková (née Dvořáková) (died 1905).
Suk began to compose his funeral symphony at the beginning of 1905, about eight months after Dvořák's death. The composition was titled after Asrael (Azrael), known as the angel of death in the Old Testament and as the Islamic carrier of souls after death. The work is in five movements. Suk completed the sketches of three movements less than a half year later. On 6 July 1905, while Suk was in the middle of the work, his wife Otilie died. Although the composition was to be also a celebration of Dvořák's life and work, the desolated composer rejected the optimistic tone of the rest of the work. Suk himself recalled:
Suk completed the score on 4 October 1906. He dedicated the work "to the exalted memory of Dvořák and Otilie", in particular the last two movements to Otilie.
The symphony was premièred on 3 February 1907 at the Prague National Theatre, conducted by Karel Kovařovic. Karel Hoffmann and Jiří Herold, members of the Czech Quartet, attended the premiere as the concertmasters of the orchestra of the National Theatre.
The composition is in five movements:
The influence of Dvořák's composing style, apparent in Suk's previous work, is not noticeable in this composition, according to Vysloužil, who writes that Suk develops his musical language rather toward modern polyphonic and harmonic techniques. Suk included several music quotations in tribute to his father-in-law and wife, including quotes from Dvořák's Requiem and opera Rusalka.
