We want to make the melodic line sing in this piece. Start with a warm rest stroke, playing over the middle of the soundhole and continue using rest stroke for the melody wherever possible. I have indicated the picking hand fingering for the first eight bars and I often leave the finger down on the adjacent string and leave it there until the next note or chord is needed. For example; in bar 2, I play the E melody note rest stroke and leave the finger resting on the third string while the bass note is plucked. The finger is then already on that string to pluck it in the middle of the D chord on beat 2. This kind of technique can be used a lot if you organise the picking hand fingering accordingly; it also increases security and tone control. If you go carefully you should see how this works for the first 8 bars.
At bar 9 we get repeat of the main theme with a different ending, leading to what would nowadays be called a chorus at bar 17. Aim to keep the melody nice and smooth (legato) and the accompaniment well articulated. At bar 20 you will need a barre across five strings at the 7th fret and bar 22 will need a four-string barre at the 2nd.
