One item on my TO-DO list is hooking up an electric guitar to an oscilloscope and frequency analyzer and do a video and/or blog post about the applied physics of heavy metal guitar sound.
There are tons of tricks employed in guitar playing to create interesting sounds by manipulating harmonics, by both the guitarist and the effect and amplifier signal chain.
Most guitarists that use these tricks are completely unaware of the physical phenomena involved. And the non-guitarist physics geeks always enjoy when I give a short demo with lots of distortion and artificial and natural harmonics tricks.
- djaychela 10y agoI'd look forward to seeing that - I teach music tech and having done that with a class singing a note and seeing the different harmonics in each person's voice is interesting, and seeing that applied to a heavy guitar sound would be interesting - as you say, there's lots that players do that they don't realise they are doing, and it will also give an understanding of what's possible to those who would then take that on board and use the techniques uncovered by it.
- jononor 10y agoYes lots of tricks. Picking/strumming close to the bridge versus at the middle. Pinched harmonics. Strumming past the nut. Natural harmonics at nodes of overtones. Exciting the strings by hitting body instead of strings.
