E 13sus4 Chord
How the E 13sus4 chord is built: its notes, its interval structure, and where it fits.
The E 13sus4 chord contains 6 notes: E – F# – A – B – C# – D. It belongs to the suspended family of chord qualities. Like every chord, it is defined by the distances (intervals) between its notes, not by any one instrument — which is why the same formula names the chord whether it is voiced on a fretboard, a keyboard, or a choir.
