A Melbourne musicologist has found a piece by Vivaldi written in 1754. The find is being described as the biggest Vivaldi find in 75 years. “The work is an 11-movement Dixit Dominus based on Psalm 109 for choir and orchestra, intended to be played in church. But Dr Janice Stockigt suspects that because of a lack of additional notation on the score, this might be its first performance ever.”
