This is one of Vera Hall's three piano pieces, "Sun and Moon".
Composed in 1756, it is a piano sonata.
A sonata is a multi-movement musical genre, with a single sonata generally taking about 15-20 minutes to perform.
Unlike other common piano pieces, a sonata is much more complex, requiring the performer to possess exceptionally high piano skills, as well as strong expressiveness and tension, making it an important tool for evaluating a performer's level.
Even the slightest weakness or lagging stamina would prevent one from playing it smoothly.
In the world piano difficulty rankings, "Sun and Moon" is placed ninth.

The last time, she left Earth in 1782.
Before her departure, she had not made her piano scores public.
