Cello harmonics, redux.?

Question: Cello harmonics, redux!.!?

Lisa (bless you) answered my first !? on harmonics brilliantly!. Unfortunately, I phrased part of the !? incorrectly!. There is another kind of harmonic used in cello writing, where the score prints a small open circle above the written note, which I think are natural harmonics!. Not sure; but if so, can one achieve a harmonic this way for all written notes!?!? So confused here!. Many thanks for your time in advance!. MattWww@QuestionHome@Com

Best Answer - Chosen by Asker:

A circle above written notes means one of two things: open string, or natural harmonics!. These are played by touching the string lightly on the note instead of pressing it!. And not all notes will give a sound when pressed!.

The notes which can be touched are as follows -

On the cello A string, from lowest to highest: (middle C is C4)

C4 (gives an indistinct E6)
C#4 (gives an indistinct C#6)
D4 (gives an A5)
E4 (gives an E5)
A4 (same pitch)
E5 (same pitch)
A5 (same pitch)
C#6 (same pitch)
E6 (same pitch)
G6 (same pitch)
A6 (same pitch)

The positions are the same on the other strings, and they hold true for ALL string instruments, including the guitar family!.Www@QuestionHome@Com
