The falseta is written in 3/4 time with thick bar lines between beats twelve and one. Unless otherwise indicated, use your thumb for all the downstemmed notes. Capo at second fret.
The idea is to keep the bass strings ringing under the trebles as much as possible. In the first compás, at beat four the thumb plays the fifth and fourth strings to finish with the ring finger on the first string at beat six. In the second compás, for the Bb7 chord, barre with your index on the first three strings, slur with your little finger and use your ring to fret the double D on the fifth string. At the end of the Bb7 chord, keep the tip of your index on the third-string Bb as a way into the A9b chord.
