Tú Me Acostumbraste in A#

Tú Me Acostumbraste in A#

El cubano Frank Domínguez compuso 'Tú Me Acostumbraste' en 1952, y su compatriota Nat King Cole la grabó en español para la eternidad. La paradoja de la letra — 'tú me enseñaste a querer, me enseñaste a olvidar y ahora me enseñas a sufrir' — mueve a cualquier corazón. La apertura Cmaj7-C7-Fmaj7-Fm es uno de los movimientos modales más refinados del bolero cubano.

Tú Me Acostumbraste 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# (ascending unison), A# to D# (ascending perfect fourth), D# to D# (ascending unison), D# to D (descending half step), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to G (ascending 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 G to A# by minor 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.
