What is the meaning of the term 'senza' in music?

The term 'senza' in music originates from the Italian language and translates to "without." It is used in musical notation to indicate that a particular element should be omitted. For example, 'senza sordino' means "without mute," directing the performer to play an instrument without the use of a mute. This instruction helps convey the specific sound quality desired by the composer. The other terms provided do not accurately capture this meaning: 'with' refers to inclusion, 'less' suggests a reduction, and 'heavily' conveys a specific intensity, which does not relate to the concept of absence or omission. Therefore, 'senza' is highlighted as indicating the lack of something in the musical context.
