Usted in A#
Usted in A#
Gabriel Ruiz compuso 'Usted' en 1943 con letra de José Antonio Zorrilla. El uso del tratamiento formal 'usted' para dirigirse al ser amado crea una tensión poética única —respeto y deseo simultáneos. Luis Miguel la grabó en el álbum 'Romances' (1997), alcanzando millones de ventas. La progresión menor con Bdim7 como acorde de paso le da la oscuridad elegante característica del bolero clásico.
Usted in A#
A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through A# to F (descending perfect fourth), F to D# (descending whole step), D# to C# (descending whole step), C# to G# (descending perfect fourth), G# to A (ascending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from A to A# by half step.
Scales for Improvisation
A# major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, A# Mixolydian adds the flat seventh for an authentic blues-rock edge.
