Part 2 Teachers as Stars Modesto had teachers build super pinna, large construction paper ears to change their perception of sound then we invited teachers to use their new ears to listen to each other. We invited teachers to play their instruments on stage at Symphony Hall. Krumhorn, recorder, saxophone, xylophone, violin, trombone, drum, and thumb piano. They also sang. Meanwhile we roamed the hall measuring sound levels with decibel meters and listening to how the sounds changed at different positions in the hall.
Teachers play their instruments on stage at symphony hall.
We discussed the science of each instrument here are some basic explorations of musical sound. How sound bounces off the open end of a tube. Harmonic Phonecord , observe how standing waves create harmonics of instruments. Slinky in Hand , a study of longitudinal waves in wind instruments. Vertical Slinky , the standing waves in a tube closed at one end.
