Vol. 1 of the new critical collected guitar work of Fernando Sor contents the advanced studies op. 6 and 29. Guitar Heritage edition: “ Our editor Erik Stenstadvold is a noted expert on 19th century guitar music and publishes regularly in leading professional journals such as ‘Soundboard’ and ‘Early Music’. His life-long preoccupation with Sor and his music, both as a performer and researcher, has resulted in an unsurpassed edition in terms of scholarly accuracy and practical usefulness. All relevant early sources have been consulted, often several different printed editions and manuscripts of a particular work. In each case the most dependable source has been chosen as copy text, on the basis of historical evidence and textual reliability. Variances and errors in the original scores are corrected and discussed in the comprehensive critical commentaries. All volumes contain detailed introductory notes that place the individual works in their historical context and discuss particular notation problems. Suggestions for the interpretation of ornaments are also provided. In Volume 1 and 2 (Studies), Sor’s likely purpose of each individual study is discussed in relation to the technique and fingering principles he describes in his 1830 Méthode.”
