This example demonstrates how to write polyphonic or instrumental music on Overleaf, using M-Tx (.mtx) syntax.
This was made possible with a custom latexmkrc file. The music piece examples here were taken from the M-Tx documentation.
This is an example letter to illustrate the use of the brownletter.cls LaTeX class file.
