Silent Musical Direction, also known as Tacet (5 letters), is a musical term used to indicate that a certain instrument or voice should remain silent during a particular section of a piece of music. It is usually written in the form of a directive, such as 'tacet' or 'solo tacet'. This term is often used in classical music, but can also be found in other genres. It is an important tool for composers and conductors to create the desired soundscape.
