It's fairly intuitive that when one does a harmonic on the 12th fret, that the string is made to stand still at the 12 the fret, while the the string vibrates in two sections; from the nut to the 12th fret, and from the 12th fret to the bridge.
A seventh fret harmonic divides the string into three section; from the nut to the 7th fret, from the 7th to the 19th fret, and from the 19th to the bridge. That the string is standing still at the 7th fret, where it is touched, is fairly obvious; it's something kinda interesting to have pointed out, when one is first essaying harmonics, that the string is also standing still at the 19th] fret, where it is not touched. And, of the same interest that if the string is touched at the 19th fret and not the 7th, the same harmonic is heard as a result.
The points at which the string is standing still are called nodes, and as harmonics get higher, the string is being divided into more sections, and there are more nodes along the string length where the string will be, or should be, standing still. These nodes are, by default, easily avoidable for 12th and 7th fret harmonics, but a 5th fret harmonic introduces a node right about in the area where one habitually locates the right hand for playing. This means that one is more likely to be inadvertently trying to energize the string at the node point, which defeats ones purpose, and mitigates against the success of sounding the harmonic. So, one has to anticipate where a node point may be in the right hand section of the string, and avoid playing there. Of course, the need for this care is exacerbated as higher and higher sounding harmonics are emp0loyed, for which the the number of nodes keeps increasing. That is the basis for the rationale behind the earlier suggestion that ponticello hand location helps.
My experience is that the quality of harmonics depend on the strings you use, so you could try a different set of strings (different brand, different tension, carbon vs nylon). It also depends on the guitar but far less than on the strings.dory wrote: ↑Thu Aug 10, 2017 9:17 pmBY the way, I have heard that some guitars have poor harmonics but my guitar does have a solid wood top and my teacher can get a loud 5th fret harmonic on it so the problem is with me. Not my instrument. I have heard that i some cases the problem is with the guitar-- especially guitars that have laminate tops but have no idea if I am right.
