I like to share that cartoon from the 19th century with you. Maybe it is well known, I don't know.
Wilhelm Busch lived in the neigborhood where I live now, and this cartoon shows me how very well Busch watched pianists. Isn't it strong how well the musical emotions are given back in the cartoon? E.g. the "Adagio con sentimento" or others?
This cartoon, colored, hangs as picture in the near of my piano, in order to inspire a bit, how to play to get that effect on a listener ...

I try a translation of the beginning:
The virtuos
A new years concert
To the new year welcomes here
a virtuos on the clavier
He leads you with treat and favor
through the wonder of his art
What do you think about that? Have fun!
