Rhythm Chaser is a Music rhythm reading program. I developed it out of some work Diane and I did with two of our Grandkids during some Zoom sessions in the Covid19 lockdown period.


If you can read music and feel like whiling away a few moments in (probably) utter frustration then this is for you!


It works on Windows MacOS and Linux (see note below) and you can play your responses back on the computer keys or via a midi keyboard.


Sadly, no app for Tablets and phones yet but you never know!


Download either the 32bit or 64bit version according to your computer. If you're not sure the 32bit one should work anyway on Windows and will give a warning on a 64bit Mac but will still work. If you are a Linux user I'm pretty sure you will know what system you have. Some windows computers (possibly older ones) may need a few extra files in order to run the app so let me know if you get an error message when you try to run it and I'll sort that out.


If you are updating from an earlier version you might want to move your old 'mydata' file into the new version. Then you will still be able to see your overall test results.


You might get the usual warnings that you are trying to run a program from an unknown developer etc. but The program has been submitted to scrutiny by lots of anti-virus programs (see results here).



Windows 64bit version 1.2

IMPORTANT - There is a slight problem with the Linux version where the very first test you play in a new session will often show far more mistakes than you really made or stutter a bit. To avoid your accuracy statistics being affected by this, when you first run the program just start a test then cancel it before it ends. After that all should be well.

Version history



11/08/20 Version 1.2 (Windows, MacOS and Linux)


1. You can repeat tests until you are happy (or fed up!)

2. In the Results window you can now play back your last test.

3.  The skill levels have been redesigned slightly

4. Midi play on Windows uses better random note choices

5. Options (mode of test, tempo, midi or keyboard input etc.) are now saved with Scores data.

Bugs cured:

Tempo slider now cannot be changed during a test.

Graphical Results display was inaccurate if the tempo was changed from when the test was run.   



30/07/20 Version 1.1 (Windows and MacOS)


1. Now works on MacOS

2. Midi input in addition to computer input is possible.

3. Tempo control over a wide range

Bugs fixed:

If the user played no notes at all the accidental 'division by zero' has been corrected. If you suffered from this then just delete your 'mydata' file and start again to keep a track of your accuracy progress.
