Back in May TED -Ed published a lesson about how sound is produced through brass instruments. Recently, they released a similar lesson about the physics of playing a guitar. The high notes of the lesson are focused on how notes and chords are produced and how the sound travels from acoustic and electric guitars. The lesson also explains the significance of guitar frets and how those make a guitar different from other stringed instruments like the violin. The lesson’s video is embedded below.
I’ve added The Physics of Playing Guitar to my list of my favorite TED-Ed science lessons.
