Selecting Materials for Musical Instruments: a Case Example with a Xylophone
Humans have been enjoying music made by instruments for a long time. But how do different types of instruments actually make sound? And how would be select materials for said instruments based on their sound-producing method? This interactive lecture introduces the Hornbostel-Sachs musical instruments classification system as a way to start this discussion. A xylophone is used as a case example for chosing materials based on the properties required for the final product. An option hands-on activity of building an instrument from household materials is included.
