Reggae is a genre of music that originated in Jamaica in the late 1960s. It is known for its distinctive rhythms, which are typically based on a strong bassline and offbeat rhythm guitar. While "reggae" is the most common term used to describe this music, there are other words that can be used as synonyms. Some of these words include "roots," "dub," "ska," and "dancehall." "Roots" refers to reggae music that has a strong focus on social and political issues, while "dub" is a type of reggae that emphasizes the use of reverb and echoes. "Ska" is a precursor to reggae that originated in Jamaica in the late 1950s, while "dancehall" is a more modern style of reggae that is heavily influenced by hip-hop and electronic dance music.
