This study focuses on a guitar duo transcription of four keyboard sonatas composed by the north German Cantor, Christian Gotthilf Tag (1735-1811). While the works were never published and the original manuscripts are lost, the music survives in manuscript copies made by K.H.L. Pölitz, which have served as the source. After a brief discussion of the composer and his life, the author explores transcription techniques used in previous duo transcriptions. The study gives a detailed rationale for the editorial methodology used, with examples from the present transcriptions. A separate volume includes the sonata transcriptions laid out in parallel to the keyboard edition, and provides brief performance instructions, mostly regarding ornamentation. The four sonatas add up to a collective length (including repeats) of approximately 60 to 70 minutes of music.
