Hi Elaine,

Agreed! I see absolutely nothing wrong with that, and didn’t intend to imply 
otherwise. I was just pointing out that applying consistent assumptions about 
voice-leading and traditional suspension resolutions highlights the ambiguity 
in the notation “Csus7”: it could mean

    <c e g> + b, suggesting a [fixed-root] resolution to <c e g> + a  (i.e., 
7-6 sus)

or

   <c g bf> + f, suggesting a [fixed-root] resolution to <c g bf> + e (i.e., 
4-3 sus)

That’s why I strongly prefer the notation “Csus7” (or even something like the 
awkward “Csus+7”) only if you mean the [relatively rare] first example, and 
“C7sus4” if you mean the [far more common] second example.

Cheers,
Kieren.
