064 Gregorio Allegri composed this sacred work in the 1630s. It was written for use in the Tenebrae service during Holy Week. Pope Urban VIII loved the piece so much, that he forbid it to be performed elsewhere outside of the Sistine Chapel. For over 100 years, Allegri's 'Miserere mei, Deus' was performed exclusively in the church. Anyone caught with a transcription of the piece outside of the chapel could be immediately excommunicated from the church. In 1770, a 14-year-old Mozart was present at one of the performances while touring Italy with his father. After hearing the piece once, the story goes,, Mozart transcribed the work entirely from memory and even made corrections.
The work is probably most famous for its Victorian embellishments for a solo treble (Laura Brayford here) who has to sing a top C several times. I remember the look on the faces of some of the girls in the audience when she sang it first time – absolute astonishment! A heroine made overnight.
