Beautiful! although I would have preferred that they were wearing period costumes and playing in a “salon” setting with the painting on the wall behind. The white church and black garments look so sterile, compared the the rich opulence of the painting.
What instrument is that keyboard? It is not a harpsichord. Do you know the name of it?
And the keyboardist — is he about 12?
Possibly a clavichord? The keyboardist looks to be in his twenties, IMO.
It’s a baroque organ.
