Sur in G

Sur in G

Sur in G — Aníbal Troilo / Homero Manzi's tango. Use Harmonic Minor and Aeolian scales to capture the dramatic tension of these changes. Chords: Gm – D7 – Cm – A# – F7 – D#.

Sur 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 C (descending whole step), C to A# (descending whole step), A# to F (descending perfect fourth), F to D# (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from D# to G by major third.

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.
