Silent Witness: What is the theme song? What are the words to John Harle's Silencium?

While Dr Nikki Alexander (Emilia Fox) and her fellow forensic pathologists uncover the truth behind crimes using scientific techniques - the “silent witness” alluded to in the title, they are always introduced by a yearning, rather melancholy piece, sung in Latin.

This piece is called Silencium, and was written by John Harle. Featuring soprano Sarah Leonard, it was used on Silent Witness from series two onwards. In 2018 an updated version was introduced.

The lyrics are

Testator silens / Costestes e spiritu / Silencium

Angeli silens / Costestes e spiritu / Silencium

Which translates to

Silent Witness / The spirits that also bear testimony / In silence

Silent Angel / The spirits that also bear testimony / In silence

The word “costestes” is unusual and not a word in regular Latin but is derived from ecclesiastical Latin, the version of the language used most in the Catholic Church, which conducted mass in Latin until the 1960s.
