Tacet

In vocal polyphony and in orchestral scores, it usually indicates a long period of time, typically an entire movement.

In more modern music such as jazz, tacet tends to mark considerably shorter breaks.

A word by which the performer is to understand that the instrument with the name of which it is conjoined is to be silent: a Violino Tacet; the violin is not to play: Oboe Tacet; the oboe is silent.It was common for early symphonies to leave out the brass or percussion in certain movements, especially in slow (second) movements, and this is the instruction given in the parts for the player to wait until the end of the movement.

The phrase tacet al fine is used to indicate that the performer should remain silent for the remainder of the piece (or portion thereof), and need not, for example, count rests.

The piece's first performance lasted a total of 4 minutes and 33 seconds, without a note being played.
