E ionian scale — chords and intervals
The harmonized E ionian scale produces the same chord family as the major scale, forming the reference point for all diatonic harmony. Every chord built from this mode occupies a clear functional role: tonic, subdominant, or dominant. The diatonic chords of E ionian are EMaj7, F#m7, G#m7, AMaj7, B7, C#m7, D#m7b5. The I-vi-IV-V turnaround is a classic pop foundation, while the I-iii-vi-ii-V chain creates elegant descending-fifth motion ideal for standards and ballads. Commonly used in Pop, Classical, Folk, Country. Notable players include The Beatles, Bob Dylan, James Taylor.

Degree-by-Degree Analysis
The I chord (EMaj7) is the tonic — the gravitational center of the key. The ii chord (F#m7) is the minor subdominant, commonly used to approach the V chord. The iii chord (G#m7) functions as a substitute for the I or vi. The IV chord (AMaj7) is the subdominant — it adds motion and moderate tension. The V chord (B7) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (C#m7) is the relative minor — it brings emotional color and depth. The vii° chord (D#m7b5) is the diminished — the most tense, rarely used alone, usually leading to the I.
