Invented in the 19th century, the mechanical metronome allows for precise measurement of short time intervals. The device has a pyramidal shape with a slanted side, where a movable pendulum is placed.
By swinging from side to side at equal intervals, it helps control and synchronize the frequency of actions without losing the rhythm. This device is most commonly used in music — during rehearsals and concert performances.
The metronome’s construction also includes a scale that allows adjusting the desired movement frequency. The higher the weight is placed on the pendulum, the lower the frequency, and vice versa. Today, mechanical models have largely been replaced by electronic ones, which often include a built-in tuner for synchronizing musical instruments.
History of the metronome
The metronome was invented in the early 19th century. The invention is credited to the scientist Dietrich Nikolaus Winkel from Amsterdam, but it was the mechanic and pianist Johann Nepomuk Mälzel who gave it practical application.
After improving Winkel’s metronome, Mälzel organized its production in the Netherlands. At that time, the primary purpose of the device was to measure the tempo in musical compositions. The famous composer Ludwig van Beethoven made the invention widely known in Europe. He was the first to mark tempo indications in sheet music using the abbreviation MM (Mälzel’s Metronome), followed by a number, such as MM30, indicating 30 beats per minute.
In 1895, German entrepreneur Gustav Wittner began mass production of the metronome. He patented the invention and initially produced the classic Mälzel model, later developing improved versions. The Wittner company, named after him, became known worldwide and remains a leading manufacturer of high-quality mechanical and electronic metronomes.
Initially, the metronome was used only by professional musicians and composers. However, it gained popularity beyond music. In 1923, the American artist Man Ray used a metronome in his sculpture “Object to Be Destroyed” — a metronome with a photograph of a woman’s eye attached to the pendulum.
In 1957, Ray’s work was stolen from an exhibition hall in broad daylight by Parisian students, who destroyed it with a revolver shot in front of numerous witnesses. This event did not harm the artist financially — on the contrary, it brought him even more fame. Ray received a significant insurance payout and produced 100 replicas of the piece, each named “Indestructible Object.”
Speaking of the metronome's historical significance, one must mention the Siege of Leningrad (1942–1944). During the radio blackout, the metronome was used to warn the city’s inhabitants of air raids and artillery attacks.
50 beats per minute signaled safety, while 150 beats per minute indicated extreme danger. This historical use was later commemorated in the musical piece “Leningrad Metronome,” with lyrics by Matusovsky and music by Basner.
Types of metronomes
Mechanical metronomes were widely used until the late 20th century. Today, however, they have been almost entirely replaced by electronic models, which are more precise and functional. The leading manufacturer remains Wittner, a company renowned since the 19th century.
Electronic metronomes have a different appearance and more features. They are no longer pyramids with pendulums but compact plastic devices with buttons and digital displays. Their main features include:
- Compactness. Electronic metronomes are lightweight, flat, and easy to carry in a pocket, folder, or bag.
- Wide tempo range. Modern models cover a range from 30 to 280 beats per minute.
- Multifunctionality. Users can replace standard clicks with beeps or other sounds.
- Memory for saving rhythmic patterns with playback options.
- Additional built-in tools: tuner, pitch pipe, recorder, and timer.
- Use in the dark. Backlit displays allow easy tempo adjustments in low light conditions.
If Mälzel and Wittner could see these modern features, they would surely be amazed. Modern electronic metronomes surpass mechanical models in almost every aspect, except one: they require power to operate. Mechanical metronomes, on the other hand, function with a simple spring mechanism and do not need charging.
