Martín Palmeri began to work on the Magnificat dedicated to mixed choir, soprano and mezzo-soprano solo, string orchestra, bandoneon, and piano in 2010. He was guided by an idea to create a piece, which would be stylistically and emotionally close to the Misa a Buenos Aires – Misatango, yet much more difficult for the performers, and more sophisticated as far as the rhythm and polyphony are concerned. The composition was completed in 2012 and its world premiere took place in Milan. The source of the text of the Magnificat is the Gospel of Luke (1:46-55).
