You may find that the animations on this page pause from time to time. Be reassured, this is just an issue with the flash movies. The program doesn't have these issues. For details see Animation glitches.
It can also play its animations at any tempo you like.
This is an animation from Bounce Metronome Pro. To vary the tempo, try other time signatures etc you need to download the program.
Try clapping to the bounces in this swing rhythm. Do you see how easy it is to clap exactly on the beat? This is why Bounce Metronome can be used entirely visually without the sound, as a silent metronome. This bounce approach is a style often used by conductors as a way to show the moment of the start of the beat very precisely.
"The motion is like bouncing a golf ball on pavement. Your performers must be trained to play exactly at the bottom of the beat."
P 19, Brock McElheran, "Conducting Technique for beginners and professionals".
When you run the program with sound, the visuals help you to play exactly on the beat and in time, even for rhythms that you may normally find a bit tricky such as perhaps ones with swing, syncopated rhythms etc. This makes Bounce Metronome Pro eminently suitable for practicing all kinds of rhythm with irregular beat patterns.
Since it can be used as a completely silent metronome it is also useful for situations where you don't want to hear the beats, or for use as a metronome for deaf musicians.
You may see pauses and stutters in the animations on this page. This can be caused by streaming issues depending on the bandwidth of your connection, or by the CPU load on your computer.
The program itself doesn't have these issues in the same way. Each frame is created by working out the position for the visuals, at the moment it's created, so that's a different situation from a playback of a previously recorded video.
Low frame rates for 3D graphics in the program itself
In the program itself you don't get these timing glitches, but you may get a low frame rate with the 3D graphics, especially if you have an older machine since 3D graphics are CPU intensive.
So, sometimes it works the other way that the video animations are better than the program. To make animations like this, you can use the EXPORT ANIMATIONS window (Ctrl + 234 in the program). When you play your exported animations, make sure you have nothing else running that's CPU intensive (check the CPU column in the Processes tab in Task Manager Ctrl + Alt + Delete).
