Giant Steps in A
Giant Steps in A
Coltrane's revolutionary composition divides the octave into three equal major-third intervals (B-G-Eb), creating a harmonic labyrinth that redefined jazz harmony.
Giant Steps in 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 C (ascending minor third), C to F (ascending perfect fourth), F to G# (ascending minor third), G# to C# (ascending perfect fourth), C# to G (ascending tritone), G to E (descending minor third), E to D# (descending half step), D# to B (descending major 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 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.
