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