What is the third harmonic for a violin string?

The third harmonic is the third note in the harmonic series. It is produced when the string is divided into three equal parts, with the nodal points at 1/3 and 2/3 of the string length. The frequency of the third harmonic is three times the frequency of the fundamental.

For example, if a violin string has a fundamental frequency of 110 Hz, the third harmonic would have a frequency of 330 Hz. The third harmonic is an important part of the violin's sound, and it gives the instrument its characteristic bright and rich tone.
