No Moon at All in A

No Moon at All 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 F# to C# (descending perfect fourth), C# to E (ascending minor third), E to B (descending perfect fourth), B to D (ascending minor third), D to A (descending perfect fourth), A to D (ascending perfect fourth), D to C# (descending half step), C# to D (ascending half step), D to G# (ascending tritone), G# to C# (ascending perfect fourth), C# to C# (ascending unison), C# to G (ascending tritone), G to F# (descending half step), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to B (descending perfect fourth), B to A (descending whole step), A to C# (ascending major third), C# to G (ascending tritone), G to F# (descending half 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 F# to F# by unison.

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.
