The Diarmonia edition, founded by the musician Mauro Caturano, was born from the need to provide a stable point of reference in the complex world of production and distribution of musical works to both established composers and young artists who are about to publish their first compositions.

Diarmonia is inspired by the desire to combine the rebirth of a "cultural space" with a high-profile musical proposal that embraces the musical work at 360°. The publisher's mission consists in supporting and promoting music through the publication of new works, transcriptions and arrangements of existing pieces for different musical groups, as well as the publication of unpublished pieces and books from various historical periods, without neglecting educational works, band music and musical essays, all distributed through a dense sales network.

For some compositions, the edition uses a technical-scientific and editorial committee, which examines and evaluates the artistic validity of the works before proceeding with publication.

Another peculiarity of the Diarmonia edition is that of assisting its authors in the complex and articulated world of the music industry, providing them with important information regarding copyright, related and publication rights and copyright.
