A type of soul music that emerged from the Southern United States. The music originated from a combination of styles, including blues , country, early R&B, and a strong gospel influence that emanated from the sounds of Southern black churches. Bass guitar, drums, horn section, and gospel roots vocal are important to soul groove. This rhythmic force made it a strong influence in the rise of funk music. The terms "Deep soul", "Country soul", "Down-home soul" and "Hard soul" have been used synonymously with "Southern soul"
