text: Stopping a note on one string, for example first finger "E" on the D string, and having another finger just touching the string a fourth higher, in this case on the position of the note "A", produces the fourth harmonic of the "E," sounding a tone two octaves above the note that is stopped, in this case, E. Finger placement and pressure, as well as bow speed, pressure, and sounding point are all essential in getting the desired harmonic to sound.
