Tres Lindas Cubanas in A#

Tres Lindas Cubanas in A#

This danzón by Antonio María Romeu, updated as a mambo for Orquesta Aragón, celebrates three lovely Cuban women. The A section weaves chromatic color chords (E7, Em7) through the G major framework, while the B section (coro) drives a no-nonsense V7-I-II7-V7 montuno over the classic tumbao.

Tres Lindas Cubanas 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 G (descending minor third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to G (ascending whole step). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. 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.
