AI Thread Summary
In Pedal Steel Guitar, players can achieve the same pitch by altering string thickness, tension, or length, resulting in distinct timbres. This variation in timbre is crucial for creating unique musical licks. The physical parameters involved can predict the pitch of the note using First Principles. There is potential to apply physics to predict timbre as well, and frameworks for measuring timbre have been developed. Pianoteq exemplifies this approach effectively, showcasing the feasibility of using physics in timbre measurement.

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.
 
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
