Before a concert Liszt mingled with the audience, charming them with his
witty remarks. He had a semicircle of chairs placed around the piano on
stage so that illustrious guests could sit near him and converse with
him between pieces. He added extra bits of his own invention to the
pieces he was playing, improvising cadenzas, tremolos, double octaves,
and trills even to iconic pieces like Beethoven’s “Moonlight” Sonata. He
brought his silk gloves on stage and threw them down to be fought over
by audience members. Women were said to carry his discarded cigar butts
in their cleavages. When he broke piano strings, as he often did in his
performances, people collected the broken strings and had them made into
bracelets.
