SUMMARY

The discussion focuses on the influence of physics on music, particularly through concepts such as simple harmonic motion, overtones, beat frequency, and harmonics. It highlights the historical evolution of tuning systems, specifically the transition to the 12 equal half-notes system, which is based on the twelfth root of 2. The conversation also touches on practical applications, such as the effects of distortion on electric guitar sounds and the differences in standing waves between stringed and wind instruments.

PREREQUISITES
  • Understanding of simple harmonic motion
  • Familiarity with wave properties of sound
  • Knowledge of musical tuning systems
  • Basic concepts of harmonics and overtones
NEXT STEPS
  • Research the twelfth root of 2 and its application in music tuning
  • Explore the physics of standing waves in stringed versus wind instruments
  • Investigate the impact of distortion effects on electric guitar sound
  • Study the principles of beat frequency and its musical implications
USEFUL FOR

Musicians, physics students, educators, and anyone interested in the intersection of physics and music theory.

There's a huge high school-level section in physics relating to music, specifically the wave nature of sound. The general category is simple harmonic motion. You need to have a good understanding of the basics of this domain before you think about music applications. When you do, though, search for terms like "overtone", "beat frequency", and "harmonics". Try your textbook maybe.
 
Physics in Music - tuning

Up til 18th century, tuning was done with fractions
( perfect-fifth was one-half, etc.), but as music got more complicated, a new tuning system was required. Considering that the frequency doubles when an octave is played above a bass note, the system was changed to 12 equal half-notes. You have to find a number which, when multiplied by itself 12 times, will double.
The answer is the twelfth root of 2.
When one compares the two systems, the difference
( using logarithm) of the two answers at the fifth is miniscule, but gets larger as one continues through the circle of fifths.

Hope this helps,

I did a physics project back in 6th form, looking at how applying effects ('distortion') to an electric guitar sound affected the formation of harmonics. Hours of fun with a huge amp, oscilloscope and the 60s throwback lab tech...

Definitely have a think about the difference between standing waves in stringed and wind instruments.
