This is something that would appeal very much to the Russian taste, I think. It has so much folklore and culture from that region that it will be a veritable Proustian madeleine of delight, and all the work is very well done.
I would not hesitate in calling it a masterpiece.
Perhaps it was designed specifically with that region in mind, because I cannot call this a masterpiece. The rim is coherent, so is the lid, so is the music rack, so are the legs, but they do not relate to each other at all.
I feel as though I am at a student recital with unrelated pieces and playing ranging from exemplary to elementary. This is not what I would call a masterpiece, my friend. But then, I like dry rub on my barbecue.
In terms of pieces fit together, I think it would help to look at the insides of some Russian Orthodox churches. The music rack is a lot like the divider behind the altar, and the way it all fits together feels similar to the way the churches are decorated. Here is one example, you can kind see the lacy sort of gold there:
Here is another example to show you how it all fits together in terms of layout. See how each picture has its own place. That is typical of Russian Orthodox churches.
If you enter a Russian Orthodox church, with the congregation singing call and answer with the priest, ancient melodies ringing high up into the darkness, it is truly a beautiful experience. The architecture and service are all designed to give you a feeling of respect and love. They congregation also stands for several hours:
Why not? Just paint every surface!
Then if you go anywhere is Russia, you will see lacquer boxes for sale, with scenes from typical Russian folklore:
The painting on the inside of the case is a famous scene of the Great Gate of Kiev, which is one of Mussorgsky's works. It is not uncommon for Pictures at an Exhibition
to be a Russian child's first introduction to classical music. They are all tied together because they are part of the experience of being Russian, or even being in Russia. I have no idea how it relates to Steinway!
These are the elements that I see in this artwork, and hopefully you see them, too.
