An American Songwriter columnist shares four country songs from across the decades whose vocal harmonies they find especially powerful, citing the genre's acoustic, stripped-back arrangements as ideal for showcasing tight vocal blends.

Highlights include Dolly Parton, Emmylou Harris and Linda Ronstadt's rendition of "Those Memories Of You"; The Eagles' "Seven Bridges Road" with its five-part harmony; The Glaser Brothers backing Marty Robbins on "Cool Water"; and Gillian Welch and Dave Rawlings' "The Way The Whole Thing Ends" from their album The Harrow And The Harvest.
