How does the vibration of a quantum string translate to a "particle's" mass?

[KarminValso1724]

According to string theory, all elementary particles are really 1 dimensional vibrating strings and the frequency that the strings are vibrating create different particles with different masses and other properties. But what I seem to not be able to find an answer to is how the vibrational state of a string can create a property such as mass. Can someone please explain.

Can someone please explain.

I think the simple answer is that these "vibrating" strings have apparent energy unique to the arrangements and frequencies involved which is what constitutes majority of the mass. A very small portion of massive atoms are actual physical particles, the majority is the energy of the gluons holding the quarks together.
