premise: A musician on a busy street. hypothesis: A saxophone player plays for a crowd.
neutral: A musician can have skills in many various instruments. When there is a musician on a busy street, that musician is not necessarily a saxophone player. Also, a musician on a busy street is not necessarily playing. Even if they didn't have their music or instruments with them, if they had musical skill and/or talent they would still be considered a musician in their everyday lives as well.
