In addition to the 3, 4, and 7 frets, you can find harmonics above the octave, such as at the 11th fret.

If you want to understand the physics, check out this Wikipedia article .

In addition to those natural harmoncis, you can also create what I think are called artificial harmonics where you fret the string, thereby changing its vibrating string length and therefore the frets where you can find harmonics. I think Nina Zanetti explains that process either in a video or maybe just a post somewhere here on FOTMD. For example, if you fret a string at the second fret, you can find a harmonic on the 5th.
