El Cuarto de Tula in C#
El Cuarto de Tula in C#
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 C#
C# major (or Db) sits in barre chord territory across the fretboard. Every chord demands precise barring, but the payoff is a bright, crystalline sound a half step above C that cuts through a band mix. C# is a intermediate-advanced-level key on guitar because no open strings fall within the key naturally, so every chord requires full barre technique. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through C# to F (ascending major third), F to A# (ascending perfect fourth), A# to A# (ascending unison), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to F# (descending whole step), F# to F# (ascending unison), F# to D# (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 D# to C# by whole step.
Scales for Improvisation
C# 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, C# Mixolydian adds the flat seventh for an authentic blues-rock edge.
