Rhythm and blues (R&B) music is characterized by its strong backbeat and emphasis on rhythm, blending elements of jazz, blues, and gospel. It emerged in the 1940s and 1950s and often features soulful vocals and themes of love, hardship, and resilience. R&B has evolved over the decades, incorporating influences from hip-hop, pop, and electronic music, contributing to it becoming a dominant genre today. Artists like Ray Charles, Aretha Franklin, and contemporary figures like Beyoncé and Usher have significantly shaped the genre and its popularity around the world.
