A "Jam Session" is an informal gathering of musicians who come together to play music without a predetermined setlist. These sessions often encourage improvisation, allowing musicians to express their creativity and collaborate spontaneously. Participants can include a variety of instruments and styles, making each session unique. Typically held in casual settings like homes, studios, or clubs, jam sessions foster a sense of community among musicians. They provide an opportunity for artists to share ideas, learn from one another, and develop their skills. Many famous musicians, including Jimi Hendrix and Miles Davis, have participated in jam sessions, showcasing their talent and innovation.
