We did not expect to spend five hours in the music instrument museum when we turned up - and we did not even visit the other galleries.
The musical instrument museum is quite splendid and was fortunately deserted on our visit. This was a huge advantage because to hear the sound of the displayed instruments you have to use a console sited in each room. The audioguide should really have provided this benefit.
The exhibits are pretty mind-blowing in number and quality - not just the original fortepiano made by Christofiori but five other of his creations. The whole museum is set out more or less in chronological order and traces the history of music making and the development of instruments.
Finally you can spend an hour in the afternoon in the interactive laboratory up stairs (where they had a particularly good special exhibition of Wagner's instrument "inventions".
