violin string gauge material comments
1. standing wave from ideal string
f = sqrt(T/m)/(2*L),
where T is string tension,
m=M/L is mass per unit length,
L is string playable length
2. frequency is proportional to sqrt(T),
volume is proportional to T,
3. overtone is the sound wave having freqs roughly multiples of the base freq, harmonics are the sound with the exact multiple freqs
4. thicker string has higher m, so more tension to produce the same freqency and louder volume
5. to find why a string is louder is to oppositely find how to mute is, why a string is muted is to find how to make it louder
6. response is related to material's elasticity?
7. bridge vibrates like a "lever" and pivoted to the foot under E string for lower strings (G/D/A), the foot under G vibrate to pass the sound to the sound bass which spread out to top plate.
because of this, string a A sets the overall pressure as it is direct on top, others need to match the pressure to produce balanced sound on strings, too strong A makes strong wolf tone (and
makes E muted?), a strong A needs strong E to make the bridge vibrations pivoted to the foot under E (heavier E than A is always better?), string A needs to be stable first and strong enought to produce the wolf tone(just when wolf comes out, select the medium A gauge), for this sound post needs to be straight and tight(snug, not too tight), then it's the E to match to exceed A's gauge for the same material...
8. people tend to use the following words to describe volume
darker/brighter/warm, weak/heavy/muted, thin/powerful
