SUMMARY

The discussion focuses on predicting timbre from First Principles in the context of the Pedal Steel Guitar. It highlights how variations in string thickness, tension, and length can produce the same pitch but result in different timbres. The conversation emphasizes the feasibility of using physics to establish a framework for measuring timbre, citing Pianoteq as a successful example of this approach. The key takeaway is that understanding these physical parameters can enhance the production of distinctive musical licks.

PREREQUISITES
  • Understanding of string instrument physics

In the Pedal Steel Guitar, one can easily produce the same-pitched note at three different locations, by selecting to change the string thickness or the string tension, or the length of the string.

The result will always have the same "pitch", but the diffeernce in timbre is noticeable; and even forms the basis for producing some highly-esteemed licks.

In every case, the 3 physical parameters of any such selection can be used to predict from First Principles, the resulting Pitch of the plucked note.

Can physics likewise be used to predict "timbre"?

Can First Principles be used to define a framework for the =measurement= of timbre?

It is possible and it has been done. For example, Pianoteq does that very convincingly - check it out.
