Son de la Loma in A#

Miguel Matamoros y el Trío Matamoros compusieron 'Son de la Loma' alrededor de 1916 en Santiago de Cuba; la pregunta '¿Mamá yo quiero saber de dónde son los cantantes?' se convirtió en la frase más citada del son cubano. La sección A usa dominantes secundarios encadenados (A7→Dm, G7→Gm7→C7→F) con una sofisticación inusual para la época; Matamoros tenía formación musical clásica y la aplicó al son con resultados extraordinarios.

Son de la Loma 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 D (ascending major third), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to C (ascending unison), C to F (ascending perfect fourth), F to D# (descending whole step), D# to C (descending minor third). 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 C to A# by whole 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.
