lattica2.eps (source link in file list below) : another Harmonic Lattice Diagram, Advanced -- this example shows 5-limit 12-tone Duodene, triangular lattice, using default link style, with basic labels for the key of C.

The lines changed in the original file to get the variation are shown below, with the changes shown indented.
