Musica e architettura. Le opere di Igor Stravinsky per la basilica di San Marco a Venezia

September 13th 1956, Stravinsky conducted at the basilica of St. Mark in Venice the first performance of the "Canticum Sacrum" (1955), together with the "Choral-Variations on the Christmas Carol Vom Himmel hoch...” (1955-56). This work is not only the transcription for mixed chorus and orchestra of the "Canonische Varänderungen" BWV 796-796a, but also an original and creative reinvention of Bach’s organ masterpiece of 1746-47, that has a deep relation with the architectural structure of the church. In ‘Variations II-V’ the composer introduced the chorus, but singing only the first four verses of Martin Luther’s text, and under some aspects the score reveals - like the musice of the "Canticum Sacrum" - the attraction of Stravinsky towards the music of Anton Webern.
