About a week ago I didn't know they existed. Now I have read a book about them and heard them all played in one concert by Patrick Murphy at St John's Cathedral. What a great experience! Our seats faced a simple stage with a candelabrum.
In front was a wooden chair where Patrick sat - it was just him and his instrument.
Looking up you could see the large stained glass window that reflected the shifting light as the evening wore on.
There were two intervals for wine nibbles and chat...but the focus was on the amazing music and Patrick who brought it to life for us 300 years after they were composed.
