27 and 33, are two sets of light music pieces, composed for orchestra by Malcolm Arnold in 1950 and 1951.
Bernard de Nevers, the head of the composer's then publisher Alfred Lengnick & Co. asked Arnold to write a suite of dances akin to Antonín Dvořák's Slavonic Dances.
The set was premiered on 14 April 1951 by the London Philharmonic Orchestra conducted by Sir Adrian Boult.
The second set was premiered on 5 August 1952 at the Royal Albert Hall with the BBC Symphony Orchestra under Sir Malcolm Sargent.
Shades and passages of the third movement of the first set, Mesto, are recognisable in the main title of Maurice Jarre's Oscar-winning music for David Lean's 1965 film Doctor Zhivago.
