Why wasn't I punished? This teacher used to send me out of the classroom because of my annoyance but I continued playing my harmonica outside of class too. (He got to bring me back inside again because I was distracting other punished classmates :P ). Anyway he just got used to it and allowed me to play right before starting our math class.
Its all improvisation from the heart. Hope you enjoy it.
