Creating a “tacet al fine” rest

When an instrument has no music for the remainder of a piece or movement, it is common to put a single multi-measure rest with a “tacet al fine” marking, which suppresses/replaces all music changes (time signatures, key signatures, rehearsal marks, etc.). This snippet demonstrates how to truncate a musical expression at a given measure and simply append a “tacet al fine” measure.
