A Felicidade 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 F (descending major third), F to E (descending half step), E to B (descending perfect fourth), B to E (ascending perfect fourth), E to D (descending whole step), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to A (descending minor third), A to D (ascending perfect fourth), D to B (descending minor third), B to E (ascending perfect fourth), E to D (descending whole step), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to B (ascending tritone), B to A (descending whole step), A to G (descending whole step), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to F (ascending unison), F to F# (ascending half step), F# to E (descending whole step), E to A (ascending perfect fourth), A to A (ascending unison), A to D (ascending perfect fourth), D to D (ascending unison), D to E (ascending whole step). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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 E to A by perfect fourth.

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.
