I don’t often post video of people talking. The best way to understand music is to listen—often—intensively—with concentration—without preconceptions. Today, we have a departure from  the Rifftides policy of letting the music speak for itself. Hal Galper is a pianist known to many of you for his work with Phil Woods, Chet Baker, Donald Byrd, Cannonball Adderley John Scofield. He is the leader of his own trio and has been in the bands of so many other consequential players that it would be impossible to list them all.
Mr. Galper is a teacher. Several of his instructional videos are online. In the one below, the subject is practicing. His observations can be valuable to musicians. They can also provide laymen with information that can improve the quality of their listening. To get the drift of what he suggests here, it is unnecessary to have technical knowledge beyond the basics of what music is made of.
