Chords in E major
E major is built from the notes E, F#, G#, A, B, C# and D#. Its scale carries 4 sharps. Harmonising that scale in thirds gives seven chords — 3 majors, 3 minors and 1 diminished — starting on E as the I. The chord on the fifth degree is B, a major V, so E major has the leading tone that makes a B-to-E cadence sound final.
Beyond those seven, E major commonly borrows Em (i), F#dim (iiø), G (bIII), Am (iv) and Bm (v) from the parallel minor — the mixture chords that give a progression somewhere unexpected to go.
The seven chords
Extended to four notes each, the same seven degrees give Emaj7, F#m7, G#m7, Amaj7, B7, C#m7, D#m7b5.
