J. K. Mertz was the most significant Central European guitarist-composer of the Romantic era. The volume researched and published by M Graziano Salvoni contains many first publications that perfectly complement the previous Mertz publications by Chanterelle. Volume 11 presents 12 compositions of medium difficulty in a new critical edition, created based on the autograph manuscripts from the Boije collection; some of these have not been published before. Difficulty level: 3.
