Nothing connects us to emotion quite like music; it's a power a new CPR podcast harnesses. Each episode of "Music Blocks" is about five minutes. Teachers can use it in classrooms. People of all ages can listen on their own. CPR’s Luis Antonio Perez and Rebekah Romberg are the hosts and producers. Professor Carla Aguilar is the education advisor for the podcast. She directs Music Education at Metropolitan State University of Denver.
