String Instrument Artificial Harmonic For Range?

Can string instrument making artificial harmonic with node 4th below most high non harmonic note?

has anyone really been far even as decided to use even go want to do look more like?

:blink: ?

For example: Viola highest note D7. Can harmonic be made using A6 as node (4th below)? Will sound good?

For example: Viola highest note D7.

no

Can harmonic be made using A6 as node (4th below)?

extremely difficult, but theoretically possible

Will sound good?

no

string harmonics generally stop sounding good (or being easy to execute) above fourth position or so

thanks you
