About the E♭sus4 chord
E flat suspended fourth is built from 3 notes: E♭ (1), A♭ (4), B♭ (5). The lowest note you play should be the root, E♭, highlighted on the diagram. You can play it in 12 places on the fretboard. The first shape is the most common; higher shapes make smooth changes easier in some keys.
