Why Don't You Do Right? in E

Key of 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 E to E (ascending unison), E to C (descending major third), C to B (descending half step), B to A (descending whole step), A to E (descending perfect fourth), E to A (ascending perfect fourth), A to E (descending perfect fourth), E to E (ascending unison), E to B (descending perfect fourth), B to C (ascending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from C to E by major 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.
