Released in 1995 and one of the defining songs of the Britpop era, Wonderwall opens with a chord progression that has become instantly recognisable to guitarists everywhere. The sequence moves through Em7, G, Dsus4 and A7sus4, with the two suspended chords giving the progression an unresolved, searching quality that feels both restless and oddly comforting. What makes it so satisfying to play is the way the top two strings ring open throughout, tying the four chords together into a continuous shimmer of sound while the harmony shifts underneath. The Em7 sets a pensive, slightly melancholic tone, and the progression never quite settles, lending the opening a wistful momentum that pulls the listener forward from the very first strum.
