While Claverton Manor is a substantial building, it is nowhere near big enough to give a complete overview of American life in a single era, let alone America throughout the period of colonial settlement.
(Which is the main focus of the American Museum in Britain.)

As has already been said, the museum has limited resources (both financial and available space) and is reliant on volunteer guides. To have an exhibition of American music would require the removal of other exhibits. The quilts maybe?

As Anne said, you will find out little about music in St Fagans, or the V & A. I would take that further. How much emphasisis there on nautical music in the National Maritime Museum? Music is not the focus of any museum, unless it is a museum of music. The American museum in Britain is not, and does not claim to be the museum of American Music in Britain, but is certainly is not without music.

"So why the complete lack of any exhibited pride in the rich musical heritage. I have been told that it does exist in the archives and can be viewed on request, but surely it should be on public display."

Just how would the music archive be put on display? Would a display of music score and tapes have any great significance? Miskin Man missed the music books that are already on display. (To be fair, you
would need to know exactly what you were looking for to find one of them.) They could of course play music in the museum. This has been tried in the folk arts section (currently closed for redevelopement).
Guess what? Not everyone approved.

That leaves the current live music events. This was started by Laura Brown the Education Officer because she wanted to bring American music into the museum. You know, that stuff that doesn't exist there - music. Why is there not more? Limited resources! They are reliant on funding for the current programme. If that dries up then ther will be no music.

Of course, those who think there should be a greater knowledge base of American music at the museum are free to volunteer, and make that their speciality. So if anyone asks, there is just the right unpaid
volunteer available to help.

Alternatively, they could finance the music programme so that American music is played at the museum everyday. Then somebody will disapprove, and complain that their favoured part of American life is missing.

No music at the American museum? Actually, there is more than at the majority of museums.

I have used the library at the museum on a couple of occasions. I have always found them to be extremely helpful and generous with their resources. Access is only a phone call away, to arrange a mutually suitable time.
