Russian guitarist a great propagandist of a six string guitar in Russia.Klinger was a Russian general in the Czar's army, and a talented composer-arranger. Most of Klinger's pieces are written for an 8-string guitar, with 7th=D, 8th=A, and otherwise conventional 6-string tuning. All of his works from opus 1-12 are for normal 6-string guitar, with 8-string notes appearing in opus 13 when presumably the composer began using an 8-string guitar. All of the works are playable on a 6-string instrument by raising the octaves of these notes, often written as 8va. There are arrangements of Western European pieces like Schubert, as well as distinctly Russian-sounding works, somewhat in the style of Tchaikovsky or "Pictures at an Exhibition". These are late romantic, most similar to Regondi and Coste. Klinger's pieces are mostly intermediate to advanced, but not awkward. The fingerings are clever; they are innovative and different from the typical "Carulli patterns" found in so many pieces, and they demonstrate a thorough use and knowledge of the fingerboard. A write-up of Klinger can be found in the preface to the Regondi Ten Etudes published by Editions Orphee. It was Klinger who hand-copied the Regondi etudes, which became the sole known surviving copy of these pieces. Klinger also produced hand manuscripts of pieces by Mertz, and the famous Mertz Elegy was possibly arranged in its present form by Klinger, and indeed it shows the characteristic Drop D and Drop A notes but no other extended notes. In addition to arrangements, Klinger was a superb composer in his own right. Klinger was associated with Makaroff and the guitar society in St. Petersburg, a hub of guitar where Sor and Pettoletti among others stayed for years.
