Teacher: What is jazz?
Student: I don't know, a style of playing?
Teacher: No, never call jazz a style of playing. Jazz is a concept. A composition of one minute, composed in a minute.
Student: Uh okay. (Not sure he gets that) Then what are the blues?
Teacher: The blues are a style of playing. And they will form the foundation of your training. Now play me something.
Student: Shit, where do I start. Feel so embarrassed just being here.
Teacher: Alright, then we will begin with the 12-bar blues. Now, I'll give you a walking bass line, and you will improvise a melody for me.
Student: Guess that after all these years, I am finally learning music.
