well that certainly shuld be documented! and it is in the book, but im 
not sure its worth buying just for that table. so here it is -- use 
fixed width font to display or the tables wont make any sense.

this doc addtion will be in CVS in an hour or so:

A rhythmic symbol consists of a metric letter (Table 1) that may be 
optionally preceded by a division letter: t for triplet or q for 
quintuplet, and optionally followed by any number of dots. Rhythmic 
symbols also support addition, subtraction and multiplication.

Table 1. Metric Letters.
letter	value         letter  value
m        maxima         q       quarter
l        longa          e       eighth
b        brevis         s       sixteenth
w        whole          t       thirty-second
h        half           x       sixty-fourth

The following table shows some representative rhythmic symbols.
