As an associate from the knights of St. Stefano, Della Ciaia suggested the construction of the body organ with 60 registers for the town of Pisa. It acquired four guides and five organs. Three from the organs could possibly be performed upon one key pad. An independent key pad for an harpsichord was understood as well. This is not really Della Ciaia’s just musical contribution although his legacy could rest upon this style by itself. He also constructed cantatas, public, and a combined mix of sacred and secular music. The key pad music included fantasias and counterpoint. Parts for the harpsichord had been created in sonata-like type merging a tocata, three-part canzona and two two-part parts. The rhythms vary between vertical chordaity and horizontal independence with full usage of the range from the device and an advanced style using key-related ascending and descending passages.
