First it seems like a bad idea to redefine \f ("forte"). But the main
problem is that an expression like $music cannot take articulations
(this has been ameliorated to some degree in current development, likely
appearing as 2.21 eventually).
You can achieve about the same effect with << $music <>-"o" >> namely
putting the articulation instead on a simultaneously executing empty
chord.
