Mauro Giuliani’s Gran sonata eroica op. 150 was first published in Milan by Ricordi in 1840, that is eleven years after the composer’s death. There are some doubts about its authenticity, which I discussed at length in my edition of this work in the Complete Works of Giuliani published by Tecla Editions, volume 15.
This present edition is a facsimile of that first edition of Ricordi.
