Musical tuning

In music tuning an instrument means getting it ready so that when it is played it will sound at the correct pitch: not too high or too low.

When two or more instruments play together it is particularly important that they are in tune with one another. This means that when they play the same note it is indeed exactly the same note. If the two instruments are not in tune with one another it will sound unpleasant because two notes which are very slightly different in pitch will produce a “beat”.
