La Cumparsita in G

La Cumparsita in G

Gerardo Matos Rodríguez compuso 'La Cumparsita' en 1917 siendo estudiante universitario en Montevideo. Es el tango más conocido del mundo: la melodía de Sol menor ha sido grabada más de 2.000 veces. Roberto Firpo, Gardel y Piazzolla la interpretaron. El título viene de 'comparsa', el desfile de carnaval: una procesión de melancolía rioplatense.

La Cumparsita in G

G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through G to D (descending perfect fourth), D to A# (descending major third), A# to C (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 C to G by perfect fourth.

Scales for Improvisation

G 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, G Mixolydian adds the flat seventh for an authentic blues-rock edge.
