Galileo Galilei first studied and discovered concepts involving the pendulum in the late 16th and early 17th centuries. History Ī Wittner mechanical wind-up metronome in motionĪccording to Lynn Townsend White Jr., Andalusian inventor Abbas Ibn Firnas invented an early metronome. The patent registered by Maelzel in London refers to the instrument as 'metronome or musical time-keeper'. The word metronome first appeared in English in 1815, and is Greek in origin, derived from metron-'measure' and nomos-'regulating, law'. This has led some musicians to criticize use of a metronome, because metronome time is different from musical time. Typically, every beat of a musically expressive performance does not align exactly with each click of a metronome. When interpreting emotion and other qualities in music, performers seldom play exactly on every beat expressive, flexible rubato may be used at times. Conductors use a metronome to note their preferred tempo in each section. The metronome is used by composers to derive beats per minute if they want to indicate that in a composition. Composers and conductors often use a metronome as a standard tempo reference-and may play, sing, or conduct to the metronome. Metronome practice helps internalize a clear sense of timing and tempo. Musicians practise with metronomes to improve their timing, especially the ability to stick to a regular tempo.

In the 20th century, electronic metronomes and software metronomes were invented. In 1815, German inventor Johann Maelzel patented his mechanical, wind-up metronome as a tool for musicians, under the title 'Instrument/Machine for the Improvement of all Musical Performance, called Metronome'. Musicians use the device to practise playing to a regular pulse.Ī kind of metronome was among the inventions of Andalusian polymath Abbas ibn Firnas (810–887). Metronomes may include synchronized visual motion.

These results are from an old single core 32 bit 2GHz machine running Linux, YMMV.A metronome (from Ancient Greek μέτρον ( métron) 'measure', and νομός ( nomós) 'custom, melody') is a device that produces an audible click or other sound at a regular interval that can be set by the user, typically in beats per minute (BPM). Slower beat rates may give less precision because there's more time during each sleep cycle for the CPU to do other tasks that may cause the sleep to be a little longer than requested.

I've set the delay here to 0.2 seconds = 300 bpm. For best results, minimize the task load on your machine, especially if it's single core. However, playing a sound takes more system resources than printing to the terminal, and that may impact the precision of this technique. The initial outputs are a bit sloppy, but it soon settles down to giving ticks that are within 10 microseconds of the requested interval. Here's a simple demo that just prints the difference between the requested and the measured time delay for each tick. Python 3.3+ provides time.perf_counter, which is supposed to be pretty good at measuring time intervals, although the exact precision depends on your OS and hardware. See How accurate is python's time.sleep()? for details.īut we can get fairly close by measuring the time span and adjusting the sleep delay. This is difficult to do on a multitasking operating system: it's not easy for the system to give you the exact sleep delay that you request.
