Der Pariser Tango in A

Der Pariser Tango in A

Key of 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 E (descending perfect fourth), E to E (ascending unison), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to F (ascending minor third), F to B (ascending tritone), B to D (ascending minor third), D to A (descending perfect fourth), A to G (descending whole step), G to C (ascending perfect fourth), C to C (ascending unison), C to A (descending minor third), A to D (ascending perfect fourth), D to D (ascending unison), D to E (ascending whole step), E to C# (descending minor third), C# to F (ascending major third), F to B (ascending tritone). 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.
