The Cherubic Hymn
Let us who mystically represent the cherubim and sing the thrice-holy hymn to the lifegiving Trinity--let us now lay aside all earthly cares.

So that we may welcome the King of all invisibibly escorted by Angelic hosts
Alleluia Alleluia Alleluia
This solemn beautiful hymn with its elaborate chant was orginally used during the procession of the Great Entrance  The Procession of the Offertory.

At present, it is divided into two parts: the first is sung by the people before the celebrant beings the procession with the Gifts,

And the second, immediately after the celebrant has completed the commemorations

Cherubic Hymns from Russian Composers
Chesnokov was born in Vladimir, near Moscow on 24 October 1877. While attending the Moscow Conservatory, he received extensive training in both instrumental and vocal music including nine years of solfege, and seven years training for both the piano and violin. His studies in composition included four years of harmony, counterpoint, and form. During his years at the school, he had the opportunity to study with prominent Russian composers like Sergei Taneyev and Mikhail Ippolitov-Ivanov, who greatly influence his style of liturgy-driven, choral composition.
At an early age, Chesnokov gained recognition as a great conductor and choirmaster while leading many groups including the Russian Choral Society Choir. This reputation earned him a position on staff at the Moscow Conservatory where great composers and music scholars like Tchaikovsky shared their skills and musical insight. There he founded a choral conducting program, which he taught from 1920 until his death.
By the age of 30, Chesnokov had completed nearly four hundred sacred choral works, but his proliferation of church music came to a standstill at the time of the Russian revolution. Under communist rule, no one was permitted to produce any form of sacred art. So in response, he composed an additional hundred secular works, and conducted secular choirs like the Moscow Academy Choir and the Bolshoi Theatre Choir. In the Soviet era religion was often under oppression, and the Cathedral of Christ the Saviour,[1] whose last choirmaster had been Chesnokov, was destroyed. This disturbed him so deeply that he stopped writing music altogether.
He died on 14 March 1944.
