This might be a harmonics course problem ;)

I didn't build something like that yet, but I highly recommend Peter
Elsea's Tutorials at http://www.sfu.ca/sca/Manuals/247/Max/Max.html

Beware: They are on Max not on PD, but they still include valid information
for PD as well: the concepts are the same. But there are some things to
consider, for example I don't know of a PD object "coll". qlist and
textfile aren't really replacements. A common idiom in PD is to use linked
arrays instead, where one array holds the number-names or indices of other
arrays, that in turn hold a chord or a scale. 

Esp. "Max & Pitch" http://www.sfu.ca/sca/Manuals/247/Max/ElseaMaxTuts/Max&Pitch.html
and "Max & Chords" http://www.sfu.ca/sca/Manuals/247/Max/ElseaMaxTuts/Max&Chords.html
deal with the things you want to achive. 

But as said they are in Max and don't give ready-to-use solutions for our PD
problems, but great stuff to think about.

bye,
