This is the second part of the Andante by Ferdinando Carulli (1770-1841). Follow this link for the sheet music and an MP3 recording of Carulli Andante part 1.
To play the Andante in its entirety first play part 1, then part 2 (above), then play part 1 again to finish. Notice how part 1 is in the key of A minor, then part 2 changes to C major - the relative major key.
The right hand fingering for this part of the piece is very straightforward. The thumb plays all the crotchet bass notes (the lower part has the note stems pointing downwards ). For the alternating F# and G quavers in the second half of bars 8, 10, 12 and 14 use p i p i
For the upper part (stems pointing upwards) the obvious fingering is to alternate m i
where the melody is on the second string or a i where the melody is on the first string. This means the open Gs after each melody note are always played by the i finger.
The left hand fingering is equally straightforward. The entire tune is in the first position
so use first finger for notes on the 1st fret, second finger for notes on the 2nd fret, and so on, following the 'one finger per fret' rule. The only exception is to use your 4th finger for the notes D on the 2nd string (e.g. bars 1, 4 and 5) and G on the 1st string (e.g. bars 3 and 7).
Best of luck. Hope you enjoy the piece!
