If you've watched any of that crazed acrobat's — Roman Kim's — videos, you'll have noticed he makes extensive use of false harmonics.
Those being playing almost sul tasto and keeping the string halfway between the fingerboard and its natural resting position to get that flute sound.
I've been wanting to use this technique in my compositions, but I can't get it as clean as he. Maybe it only works on synthetics or wrapped strings? I can do it best on the G string.
He also seems to be able to play up the octave this way, which I can only do sporadically (as well as accidentally play all the other partials).
Can someone enlighten me? Or do I gotta just work at it obsessively for a month?
To my mind they are not "false" harmonics, they are "fingered" harmonics. You can work this out yourself with open string (or natural) harmonics within the first octave* of each string: any place you can touch the string gently with a finger and create a clean sound you will have divided the string into some integer fraction such as 1/2, 1/3, 1/4, 1/5 - and so on. The instrument, the string, the rosin, bow and your skill with it all play a part.
I'm not talking about the traditional artificial harmonics. I find those very easy for me, since I've practised those extensively.
extremely light pressure and fast flautando.
