Currently working on the Presto Agitato from the Moonlight Sonata. I am in a dilemma regards to tempo.

I want to stay true to the historical tempo of the movement given by Carl Czerny and Ignaz Mocheles which is a very fast 92 halfnotes per minute.

There is a lot of debate whether these metronome markings are correct or not, which is another discussion. I do however think they are. But for the sake of the argument lets agree they are and their metronome marks is the best source we have for how fast Beethoven wanted us to play his sonatas.

The instruments of the time had a lighter touch and a smaller tone than todays pianos and also narrower keys, which is why I believe they could play faster and still make all the notes clear.

I have tried playing the Presto Agitato at that speed and its physically demanding and since the tone is fuller I find the arpeggios to get a bit blurred and not as clear as I have hoped.

Do you think, that because of this, it's justfiable to play it a bit slower? I am torn of trying to follow Czernys and Mocheles instructions and actually trying to make proper music.
