Teaching Resonance and Harmonics with Guitar and Piano

摘要

In a recent paper,~2 Kasar, Yurumezoglu, and Sengoren show how to use a guitar, or two guitars, to demonstrate resonance. Here we extend this idea by showing how to use a guitar or a piano (both acoustic) to demonstrate resonance, harmonics, and the properties of the musical scale. We discuss the advantages and disadvantages of each instrument. Students who know something about music can get a little more out of these demonstrations than others, but all students will observe some important and interesting phenomena in an everyday setting.
