From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head. Learners will open up cassette tapes and used tape players to see how they work. Then, they will dismantle some of the parts in order to create and design a new instrument. The How To includes a video of the sound the Audio Tape Bow makes when run across a tape head. This activity is a great for exploring the way sounds are recorded and the technology used to play it back.
