More grist for the mill:
As with the Eroica, he pushed the limits of the period's chamber orchestra, which nearly burst the four walls of Lichnowsky's salon.
Now the new sonatas were already beyond the mechanical capacity of the piano and virtuosity of the performers of his day. if played according to Beethoven's implications, it would have done damage to the close descendants of the harpisichord.
B appealed to Striecher the piano maker to give his instruments greater resonance and elasticity that the virtuoso who plays with strength and significance may have the instrument in better command for sustained and expressive tones.
As it was, the Appassionata had not been publicly performed until B had been in his grave for 12 years, so far as the records show.
This is my case thus far, for modern instruments. The man was far ahead of his time~
