It's not obvious to me whether
  c\chord #'(1 7)
should produce "c b" or "c bes".  Musically speaking, I'd look at
the key signature; if it were c major, I would assume it meant
"c b" since "b" is the seventh note of the scale.

This may be a problem for the numeric syntax.  I suppose we could
define each number as being a perfect, major, or minor interval;
users can adjust those intervals with + or - as required.
