Countdown in E

Countdown in E

Coltrane's Coltrane-changes reharmonization of Tune Up, applying the major-third cycle from Giant Steps to a ii-V-I framework.

Countdown in E

E major is arguably guitar's most powerful key. The open low E and high E strings ring sympathetically as the root, while the open B provides the fifth. This triple reinforcement gives E-based riffs and chords unmatched depth and volume. E is a beginner-level key on guitar because both the low E and high E strings ring as the root, and the open B is the fifth — three open strings reinforce the tonic chord. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through F to F# (ascending half step), F# to B (ascending perfect fourth), B to D (ascending minor third), D to G (ascending perfect fourth), G to A# (ascending minor third), A# to D# (ascending perfect fourth), D# to D# (ascending unison), D# to E (ascending half step), E to A (ascending perfect fourth), 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 C# (ascending unison), C# to B (descending whole step), B to D# (ascending major third), D# to G# (ascending perfect fourth). 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 F by minor third.

Scales for Improvisation

E 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, E Mixolydian adds the flat seventh for an authentic blues-rock edge.
