El Cuarto de Tula in A

El Cuarto de Tula in A

Carlos Puebla compuso 'El Cuarto de Tula' y la Compay Segundo y el Trío Matamoros la interpretaron; fue el Buena Vista Social Club (1997) quien la lanzó al mundo. Compay Segundo tocó los acordes de esta picaresca narrativa con la tranquilidad de quien ha vivido todo: el cuarto de Tula se incendió, y el coro pregunta con doble sentido qué fue lo que pasó. El ciclo C-E7-Am-A7-Dm7-G7 es el son cubano con dominantes secundarios encadenados: sofisticado pero lleno de swing.

El Cuarto de Tula in A

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through A to C# (ascending major third), C# to F# (ascending perfect fourth), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to D (descending whole step), D to D (ascending unison), D to B (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 B 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.
