Andantino – slightly faster (80–108 bpm).Adagietto – slower than andante (72–76 bpm).Larghissimo – very, very slow (24 bpm and under).

#200 bpm metronome code
The code has been tested on Catalina (10.15.x) to Monterey (12.4.x) with Ventura still in beta at the time of this post. It's GUI includes a slider control to adjust speed, as well as blinking indicator and a sound, to indicate tempo.

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.
