In Raffaele Calace's considerable musical production - approximately 200 opus numbers - 9 pieces are for solo guitar, obviously not including his single composition for Hawaiian guitar, Piccolo fiore op. 168. This statistical datum takes on a greater importance if we consider that Calace's other solo pieces were all for the two main instruments to which he devoted his existence, the mandolin and the cantabile lute: for these instruments he composed respectively 30 and 26 works, in addition to his handbooks, which are a fundamental point of reference for the modern teaching of these instruments. Nonetheless, it would be a mistake to consider this production unworthy of interest: it shows us the taste and charm of a period, and offers us compositions that are refined and far from commonplace. These pieces convey the emotions and intimacy of the romanticism that could be felt in drawing-room music, during the so-called "periodiche", the musical gatherings in the Neapolitan middle-class homes. The young guitarist Roberto Guarnieri plays Calace's music on a precious 1936 "Mozzani" guitar part of the collection of the Modenese luthier Lorenzo Frignani.
