harmonics in tablature

[Patrick Schmidt]

Hi all,

I'm having difficulties to indicate in tablature where to place a  
finger to get harmonics other than the first harmonic (see Ex. 1).  
The first harmonic is normally produced in the 12th fret and sounds  
in the same octave as if the string were stopped in the 12th fret  
(one octave above open string). In the case of other harmonics the  
pitch or the octave of a fretted note isn't necessarily the same as  
the pitch of the resulting harmonic.  Of course LilyPond calculates  
the fret number of a given pitch name so it's no surprise that in Ex.  
2–4 the fret numbers in tablature differ from those indicated in the  
text markups. I would like to engrave the sounding pitch of a  
harmonic in standard notation and the place where to put one's  
fingers in tablature. Is there a way to adjust fret numbers in Ex. 2– 
4? Or is it possible in Ex. 5–6 to get rid off the note head for the  
stopped position in standard notation and typeset the fret number(s)  
in single angle brackets in tablature?

Thanks for any hint!
