This falseta, written in the key of G# Hijaz (por minera), is largely based on chords constructed by diatonic fourths. This type of harmony, widely used in jazz, has the sonority which is much more ambiguous and open to interpretation than the thirds-based chords. This sonority facilitated "outside playing", or polytonal interpretation of the base harmony for improvisation.
In the flamenco environment these chords can be used to harmonize melodic patterns, characteristic for this genre, with new and unexpected chord flavors, thus expanding the palette of the flamenco harmonic expression. In the cadence (remate) on this falseta a whole-tone scale permutation is used.
