Contemporary R&B (also known as simply R&B) is a music genre that combines elements of rhythm and blues, pop, soul, funk, hip hop and electronic music. The genre features a distinctive record production style, drum machine-backed rhythms, pitch corrected vocals, and a smooth, lush style of vocal arrangement. Electronic influences are becoming an increasing trend and the use of hip hop or dance-inspired beats are typical, although the roughness and grit inherent in hip hop may be reduced and smoothed out. Contemporary R&B vocalists are often known for their use of melisma, popularized by vocalists such as Michael Jackson, R. Kelly, Craig David, Stevie Wonder, Whitney Houston and Mariah Carey.
