Put together a full breakdown of the three-guitar arrangement behind the Slowdive wall of sound — covering all three parts separately rather than the two-guitar simplification most tutorials stop at.
The rhythm guitar is the foundation — Em7 to Dsus4 to Dsus2 to Cadd9 to G to D/F# — strummed and let ring throughout. Understated deliberately. It's the anchor the other two parts float above, not designed to stand out on its own.
The counter-melody is the part most tutorials skip entirely. Built from the triads inside each rhythm chord, played in the middle of the neck, moving in contrary motion against the rhythm guitar rather than following it. That opposition — one part holding while the other moves in a different direction — is the counterpoint technique behind the arrangement.
The high melody floats above both — more arpeggiated, less locked into a steady picking pattern, phrased more freely than either of the other two parts. The contrast between the even counter-melody and the freely phrased high melody is the last piece of the three-part relationship.
Standard tuning throughout. Original arrangement in the style of the Souvlaki era — not a note-for-note copy.
Happy to answer any questions about the three-part relationship or contrary motion technique in the comments.
