Trivia
Did the Ensemble Piano also Exist in Beethoven's Day?

Modern pianos usually have three pedals. Among them is one called the damper pedal that functions to sustain the sound, and another called the una corda pedal that softens the sound.
However, in Beethoven's day, when pianos were a symbol of "high technology," many pianos were built that had four or more pedals. In Vienna, pianos built by a man named Georg Haschka were known for their multiple pedals, among which was an instrument with eight pedals. The purpose of the pedals of this era was to change the tone and timbre of the notes like the stops of an organ. A classic example of this is the so-called "Turkish" or "Janissary" (Janitscharen) pedal that, when pressed with the foot, played cymbals, bells, and drums in synchrony with the keyboard in imitation of the sound of a Turkish military marching band. This could be called a 19th-century version of the ensemble piano.
