To learn how to play the jazz guitar, you must first familiarize yourself with how the jazz music works. Like a sprinter prepares for a 100-meter dash, a jazz musician physically and emotionally prepares himself for a musical performance. The jazz musician needs to warm himself up and introduce himself and his musical style to the audience. He also needs to familiarize himself with the atmosphere and the crowd before him. However, a number of musicians can play soulfully without warming up, to the surprise of eager audiences.
