% FILE: tabdefs.tex
% This file contains some macro definitions for use with MusiXTeX.
% It was tested with MusiXTeX T.72.
%
% Most symbols will look ugly on your dvi-viewer, because I put in
% some postscript code to put a white box behind them. The postscript
% file will look a lot better. Special thanks to Stanislav Kneifl
% for helping me with this.
%
% An example of the use of these macros can be found in the file
% tabxampl.tex. For comments and suggestions, please e-mail
