St. Thomas in Mi

St. Thomas in Mi

Sonny Rollins' Caribbean calypso classic infuses jazz harmony with island rhythm, using Mixolydian and Major Pentatonic lines over a buoyant E feel. Bebop Major vocabulary fits naturally over the changes, bridging swing and calypso rhythmic sensibility. The EMaj7 – G#m7 – C#7 – F#m7 – B7 – E7 – AMaj7 – A#dim7 – A6 progression is one of jazz's most joyful settings for melodic improvisation.

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 G# (ascending major third), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to A# (ascending half step), A# to A (descending half step). 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 A to E by perfect fourth.

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.
