Inch Worm, The

Inch Worm, The 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 D (descending whole step), D to E (ascending whole step), E to A (ascending perfect fourth), A to A (ascending unison), A to F# (descending minor third), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to E (ascending unison), E to D (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from D to E by whole 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. Over dominant seventh chords, E Mixolydian adds the flat seventh for an authentic blues-rock edge.
