Mi Buenos Aires Querido in A#

Mi Buenos Aires Querido in A#

Carlos Gardel y Alfredo Le Pera compusieron 'Mi Buenos Aires Querido' en 1934 en Hollywood. Gardel la cantó en la película 'Cuesta Abajo' meses antes de morir en el accidente de Medellín en 1935. Es el tango del exilio y la nostalgia por la ciudad: el inmigrante, el emigrado, el viajante que añora el barrio. El F#dim7 —el vii°7 de G menor armónico— es el acorde que hace temblar la nostálgia en el tango; su tensión hacia Cm es inevitable como el regreso que el cantante desea.

Mi Buenos Aires Querido 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 A (descending half step), A to D# (ascending tritone), D# to F (ascending whole step), F to C# (descending major third), C# to G# (descending perfect fourth), G# to F# (descending whole step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from F# to A# by major third.

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.
