premise: A man in a black shirt playing guitar in a band. hypothesis: The lead guitarist of a major band warms up with the other members.
neutral: Just because the man plays guitar in a band does not tell us that he is the lead guitarist. We can not tell that the band is a major band, as they could be a minor bad, a new band or an old band. Playing does not indicate warming up, as they could be playing live or playing to practice.
