You play this sonata very effectively. I greatly enjoyed hearing it! Thanks so much for sharing it here.
You raise an interesting point that Haydn's music is so little rated and known. As I think about that, some possible reasons come to mind. When Haydn was young, he first taught himself the harp. Later he learned the violin and harpsichord. But generally in his time he was thought of as a composer, conductor and string player, not a pianist. Yet he obviously took a huge interest in composing his piano sonatas. That brings me to a another thought related to piano pedagogy and repertoire. Here in the U.S. (I cannot speak for elsewhere) piano students learn some Mozart, then two or three Haydn sonatas (or at least movements which is acceptable), and then assume that they have "graduated" to Beethoven. So in retrospect, they consider Haydn to have been simply a less sophisticated forerunner to Beethoven, maybe in the same way that we sometimes consider Carl Maria von Weber to be a less accomplished predecessor to Chopin, Mendelssohn, Schumann and Liszt--despite the fact that in his own time, he was considered to be a giant of the world of music. Or another example might be the old practice of having students study Moscheles' etudes before "graduating" to Chopin's etudes, the implication being that Mocheles' etudes were more pedantic or preparatory in nature. We should not forget that it was Haydn who invented sonata form and also tutored both Mozart and Beethoven in composition!
Having said that, I believe that the lasting perception of piano students, unfortunately and for a very long time, has usually been that Haydn was their helpful stepping stone or link to Beethoven--period. It's perception rather than substance, but perception more often than not becomes a person's reality.
