One of my years-old ideas about Beethoven’s piano playing is that it developed from, roughly said, “impetuous-youthful-but-rough” via “virtuosic-professional” to “stepwise declining”. First signs of that “decline” can be seen in documents from around 1800. Clear indications date from 1805 and onward.

It beautifully summarizes what I have tried to establish:
AMZ Zehnter Jahrgang, No. 19, 3 February 1808 p. 303. In a review of the trio Op. 2 by Ferdinand Ries, Beethoven’s former student, we find the following passage:
