The 12 concerti grossi published in 1744 by Charles Avison are arrangements made from harpsichord sonatas by Domenico Scarlatti. Although the 12 Concertos are arrangements, the pieces are imprinted more strongly with Avison’s style than Scarlatti’s. It is interesting to observe how Avison transformed these solo harpsichord pieces into orchestral works Concerto grosso for 7 string voices (two solo violins, solo cello and string orchestra à 4).
