Tempo app and Bluetooth receiver with my iPhone. (See an earlier post for specifics about Tempo and the Sony Bluetooth receiver) Today during a scale warm-up, I was able to reach a number of students by walking around the room to correct posture problems and reinforce what individual students were doing well. I could adjust the metronome speed on-the-fly as I walked around. I was barely even on the podium for the warm-up.
Being able to give my students meaningful feedback as the played had a huge effect on their concentration and attitude. I could see and feel that this warm-up had more intensity. The students were trying harder because I was next to them. Not that I haven't floated around the room before, but the Tempo app gave me no reason to return to the podium. There certainly was not a need for me to conduct the scales. My effectiveness as a teacher today was most certainly influenced by this use of technology.
