|Dietrich Nikolaus Winkel, Johann Nepomuk Maelzel horology|
Dietrich Nikolaus Winkel invented the metronome, weighting a pendulum on both sides of the pivot. The next year, Johann Maelzel added a scale and patented it. In 1817, Ludwig van Beethoven, a friend of Maelzel, added metronome markings to one of his compositions.
György Ligeti, influenced by the Fluxus movement, composed his Poème symphonique, for one hundred metronomes. The metronomes are wound up tightly, set to different tempos, and started together by ten performers who then leave the stage.
I’d play tennis without a net, and without an opponent. How would this be ”tennis”? I would count syllables. My serve would take six syllables. My return would take eight. Underlying rhythms would help serve my reader though fighting a built-in delay.
