In this clever and thoughtful exploration, Matthew Birkhold reveals how a simple ticking device became both liberator and tyrant, reshaping not just how we make music but how we understand rhythm, precision, and ultimately, our own humanity.

Matthew Birkhold reveals the fascinating history of the metronome that not only covers music, but touches upon dance, art, education, philosophy, physics, psychology, and sports medicine. Devised by Johann Nepomuk Maelzel in 1815, Beethoven was an early supporter, but soon Maelzel's metronome (the original M.M.) inspired passionate debates amongst musicians, conductors, composers, pedagogues, and musicologists. Birkhold has successfully unveiled the deeper meanings of an innocuous device that spells out perfect time, as opposed to human time. An illuminating read.
