Pop-soul is a musical genre that combines elements of traditional soul music with the more commercial and widely accessible influences of pop music. It is characterized by powerful vocals, often with strong emotional expression, and melodies that are catchy and easy to stay in the listener's mind. The instruments that are often used include piano, guitar, and percussion, while there is an extensive use of effects to deepen the sound. Artists such as Adele and Amy Winehouse are well-known representatives of the genre.
