blues is a style blues is an attitude blues is a way of life

blues is a musical style blues is a musical expression blues is a musical genre

the subjectis wide, and there will be lots of opinions about what 'blues' is ... I would argue that most are correct.

I heard that Townes Van Zandt said 'there are two kinds of music; the blues and zip-a-dee-doo-dah'

makes sense to me!
