The All-Night Vigil (Pre-reform Russian: Всенощное бдѣніе, Vsénoshchnoye bdéniye; Modern Russian: Всенощное бдение) is an a cappella choral composition by Sergei Rachmaninoff, his Op. 37, premiered on 10/23 March 1915 in Moscow.

The piece consists of settings of texts taken from the Russian Orthodox All-night vigil ceremony. It has been praised as Rachmaninoff's finest achievement^[1] and "the greatest musical achievement of the Russian Orthodox Church".^[2] It was one of Rachmaninoff's two favorite compositions^[3] along with The Bells, and the composer requested that its fifth movement (Нынѣ отпущаеши, Nunc dimittis) be sung at his funeral.^[3]

The title of the work is often mis-translated as Vespers. This is both literally and conceptually incorrect as applied to the entire work; only the first six of its fifteen movements set texts from the Russian Orthodox canonical hour of Vespers.

The Vigil includes three styles of chant: znamenny (in numbers 8, 9, 12, 13 and 14), a more recitational Greek style (numbers 2 and 15), and "Kiev" chant — a chant developed in Kiev in the 16th and 17th centuries (numbers 4 and 5). Before writing, Rachmaninoff had studied ancient chant under Stepan Smolensky, to whom he dedicated the piece. It is written for a four-part choir, complete with basso profondo. However, in many parts there is three-, five-, six-, or eight-part harmony; at one point in the seventh movement, the choir is divided into eleven parts. Movements 4 and 9 each contain a brief tenor solo, while movements 2 and 5 feature lengthy solos respectively for alto and tenor. The fifth movement, Nunc dimittis (Nyne otpushchayeshi), has gained notoriety for its ending in which the low basses must negotiate a descending scale that ends with a low B-flat (the third B-flat below middle C). When Rachmaninoff initially played this passage through to Kastalsky and Danilin in preparation for the first performance, Rachmaninoff recalled that:

Danilin shook his head, saying, "Now where on earth are we to find such basses? They are as rare as asparagus at Christmas!" Nevertheless, he did find them. I knew the voices of my countrymen...^[3]

Note: Numbers 1–6 contain settings from the Russian Orthodox Vespers service (Russian: Вечерня, Večérnja), numbers 7–14 settings from Matins (Утреня, Útrenja), and number 15 from The First Hour (Первый час, Pérvyj čas).

The first recording of the Vigil was made by Aleksandr Sveshnikov with the State Academic Russian Choir of the USSR for the Soviet Melodiya label in 1965 – exactly half a century after the work's first performance. Because of Soviet anti-religious policies, this record was never available for sale within the USSR, but was only made for the export market and private study. This recording still has a legendary reputation, in part because of its extremely strong low basses, but also because of the solos by Klara Korkan and Konstantin Ognevoi.^[13] The recording was first released in the United States in 1973 on the Melodiya-Angel label. The March 1974 edition of Stereo Review noted that Angel's general manager Robert E. Myers had "tracked down the recording" and "had to prevail rather heavily on the Soviet powers that be to make it part of their trade agreement with Angel".^[14]

The Russian feminist protest punk rock group Pussy Riot used the sixth movement as the basis for its protest song "Mother of God, Chase Putin Away".^[15]
