At the heart of jazz singing is improvisation, a hallmark of the genre. While many vocalists in other genres stick to the script, a jazz singer can take liberties with melody, phrasing, and rhythm, adding their personal touch to each performance. Improvisation allows them to create something new and unexpected with every performance, making each show a unique experience. It’s a skill that requires not just technical prowess but also a deep understanding of the music and the ability to communicate with the accompanying musicians in real-time.
