G-Funk is the laid-back, Funk-inspired variation of West Coast Rap. Distinguished by its whiny, cheap synthesisers, slow grooves and deep bass, G-Funk became the most popular genre of Hip Hop in the early 90s. After the success of Dr. Dre's 1992 album The Chronic – the album where he invented and named the genre – many new rap artists and producers followed his musical techniques, making it the most recognisable sound in Hip Hop for most of the early 90s. G-Funk incorporates multi-layered and melodic synthesisers, slow hypnotic grooves, a deep bass, background female vocals, the extensive sampling of P-Funk tunes, and a high-pitched portamento saw wave synthesiser lead. The lyrical content depended on the artist and could consist of sex, drugs, violence, vandalism and women, but also of love for a city, love for friends and relaxing words. There was also a slurred "lazy" or "smooth" way of rapping in order to clarify words and stay in rhythmic cadence. Unlike other earlier Hip Hop acts that also utilised Funk samples, G-Funk often utilised fewer, unaltered samples per song.
