Blues songs typically feature guitar (often slide guitar), harmonica, piano, bass, and drums, with raw and heartfelt vocals. The lyrics often reflect themes of struggle, loneliness, and perseverance, making blues a deeply personal and relatable form of music. Over time, blues has influenced many other genres, including rock, jazz, and soul, shaping the sound of modern music. Some legendary blues artists include Robert Johnson, B.B. King, Muddy Waters, and Etta James.
