Lanzetti’s compositions are exclusively for the cello. Even his early works require a surprisingly high technical ability for his time, and they become even more demanding in his later compositions. This can be seen in the use of double stops and bow strokes in Opus 1, even in the highest range of the instrument. In Opus 5, Lanzetti’s further investigations into the technical possibilities of the instrument are represented through the use of artificial harmonics, an extremely advance technique for his time. Opus 6 is somewhat different, returning to a simpler and more constant technique. His developments in technique were probably too audacious for the cellists of the eighteenth century, and therefore not suitable for publication. While he continued with his technical investigations, particularly in the handwritten sonatas (such as “Porto Mahone”), the published Opus 6 remained in “easy and elegant taste”, as indicated on the title page.
