This simple but rather haunting piece is the first part of a composition by Ferdinando Carulli (1770-1841).
Carulli was born in Naples, where he received music instruction from a priest who was an amateur musican. Carulli initially played the cello, but at the age of 20 he discovered the guitar and thereafter made it his principal instrument. In the absence of any teachers he developed his own individual style, and went on to become a leading virtuoso as well as a prolific composer for the instrument.
The Andante can be found in Carulli's Elementary Guitar Method, op 27, which was the first significant work of its kind. This classical guitar self-instruction book was published in 1810 and contains pieces and exercises that are still of value to the aspiring classical guitarist today.
There are basically two different musical patterns used in this first part of the piece. One of them is where we have a run of continuous quavers in the top line (e.g. in the incomplete bar at the very beginning, in the second half of bars 2, 4 and 6 and the whole of bar 7). Here we want to play these continuous quavers with alternating left hand fingers, mainly i m i m.
The other musical pattern is the one found in bars 1, 3 and 5, and in the first half of bars 2, 4 and 6. Here we have a two note chord as a quaver immediately followed by a quaver in the bass. The right hand fingering would be i and m for the two note chord, and p for the bass note.
If this Andante were a classical guitar performance piece for the ABRSM or Trinity College grade exams it would probably be around grade 2 standard.
