Ramón Montoya recorded this falseta in 1931 with the singer Manuel Vallejo. The first sung line is "Por los balcones del cielo" and the falseta is heard at the end of the recording. The falseta is played in the relative key of A major (A/E7) with the capo at the sixth fret. Thick bar lines appear between beats 12 and 1. I've omitted the key signature in the second staff and the golpes heard at beat 12 because of the limited space.
The first two measures of the transcription lead into the falseta over beats 7 to 12. The falseta consists almost entirely of bass-string slurs in combinations of triplets and eighth notes, so keep an eye on the time values in the standard notation. The thumb is used throughout ("q" indicates an upstroke), and taps are heard at beat 12 during the pauses.
At the end of the first staff, over beats 8 and 9 of the second complete compás, the fifth-string slur is held briefly at the fourth fret before being released. At the end of the second staff, avoid letting the open fifth string ring into beat 6 of the second full compás. After the slurred melodic line has descended to the fifth string, you want to be "aiming" for the open fourth string on beats 6 and 8.
