In my classical guitar book "Klassiker der Gitarre", edited by Martin Rätz, there is a piece which is attributed to Fernando Carulli. It has the title "Sonate" (Sonata) and the tempo Largo. No other information is given. The first few measures are like in the image.
Unfortunately neither I, my teacher, nor any of his colleagues were able to find this piece by Carulli in any other source, or any publicly available recording of this piece (YouTube, Spotify, etc).
Does someone know this piece and can confirm that it is indeed by Carulli (e.g., by giving an alternate source, opus, etc.)?
The main reason we want to find another reference is to obtain information about the tempo it should be played in. We are unsure because "Largo" implies slow tempo, and at the same time, there are a lot of fast notes in the piece. We currently interpret Largo as circa 50 eighths per minute, but we aren't certain whether the composer actually means 50 quarters per minute.
