Blues/Jazz: Jazz and blues are often compared to or paired with one another, and that’s largely due to their shared tone and themes. But what sets them apart is that jazz is known for smooth, easy-breezy vocals while blues is a little harder and more soulful. They call it the blues for a reason: it’s got pain behind its eyes.
Hip-Hop/R&B: When you thinking of traditional forms of singing, you may not immediately think of hip-hop, but it’s not all spoken-word rap. Look to most artists of the genre, and their songs feature rap, yes, but also rhythmic, rhyming song verses. R&B is cut from the same cloth as hip-hop, but features more traditional soul vocals.
