There are several versions of Vivaldi's Magnificat in G minor the earliest would most likely have been written for the Pietà and dates to some time in or around 1715. Early in the 1720s Vivaldi revisited it reworking the lower voices to make them more suitable for lower voices and adding a pair oboes for whom he expanded 'Sicut locutus est' so that he could take advantage of their novel and pleasing sound in obbligato passages. So much for the instrumental accompaniment what of the disposal of the vocal forces? Well it's specified for two cori, there's some reworking, and Vivaldi's directions on the score specify which of the two cori (or both) should sing what. But to be honest all of that is more a question of Vivaldi trying to show that he was up to date with musical fashion than anything else as the work is distinctly monochoral in its structure and conception. It's an admirlably concise and restrained setting that nevertheless manages to fit a lot of musical drama into very little space. Thus we have the chromaticism of the opening verse followed by a tripartite aria in which each of the three succeeding verses is taken by a different voice this 'aria a tre' is succeeded by the wonderfully poignant choral handling of 'Et misericordia eius', which is followed by two choral movements. These are a delight I like how Vivaldi illustrates the Lord's strength over the bass line ('Fecit potentiam') and the graphic way in which the mighty are put down and the humble are exalted. The soprano duet in which the hungry are 'filled with good things' (Esurientes implevit bonis) is downright charming while the 'Sicut locutus est' terzet which follows on from the brief 'suscepit' is a cheerful and optimistic piece of music – which must have caused a lot of raised eyebrows when it was first heard. Finally the doxology as you might expect opens with a restatement of the work's opening which gives way to a splendidly muscular traditional double fugue. Not easy to sing but a joy to listen to when it's sung well as the excellent Argentinian choir Coral Mirabilia directed by Fernando Polonuer demonstrate below. Enjoy :-).
