So What in Mi

So What in Mi

So What in E — Miles Davis's modal manifesto from Kind of Blue. The entire head lives in Dorian mode; the bridge shifts up a half step to Eb Dorian. One scale, infinite expression. Changes: Em7 – Fm7.

So What in Mi

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 F (ascending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F to E by half step.

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. Layer in the full major scale for melodic runs, reserving the pentatonic for riff-based phrases.
