Stevland Hardaway Morris, known professionally as Stevie Wonder, is an American singer-songwriter, musician, and record producer. He is widely regarded as one of the most influential musicians of the 20th century, and is credited as a pioneer and influence by musicians across a range of genres that include R&B, pop, soul, gospel, funk, and jazz. Wonder's use of synthesizers and other electronic musical instruments in the 1970s reshaped the conventions of contemporary R&B. He also helped drive such genres into the album era, crafting his LPs as cohesive and consistent, in addition to socially conscious statements with complex compositions.
