Josh, technically we could say both techniques produce an artifical harmonic, that is if we define a natural harmonic as one played on an open string, the latter technique of fretting a note and touching it 12 frets up (Harp style) effectively is the same as using the open string, you are just dealing with a shorter piece of string, the fret is stopping the string just like the nut stops the string, and we are still producing the 2nd harmonic, I think this is all semantics, Noticing, I still disagree, tune all your strings down 1/2 step or up 1/2 step, now the B string harmonic at the 7th fret is a natural note and all others are accidentals right? play all the harmonics like you outlined in your post, do all the other strings sound dead or have less volume? Tune back to standard tuning and then tune the B to a C, does the the B sound better at the 7th fret? Theoretically the nodal point we touch to make the harmonic does move slightly when we change the string length at the bridge, but only minutely and the contact surface of a finger tip is large enough to make up the difference, I think what we notice when we play the harmonic on the B string, is the intervallic difference it has relative to the other strings...........
