Set Calculator
Quite some time ago I created a simple pitch class set calculator for my students using Flash technology (I know, but I was young ...). While I wanted to do a complete rewrite maybe in JavaScript for many years, this undertaking has failed until now due to - as is almost always the case - lack of time or higher priority of other projects. Nevertheless, the program serves its purpose. So if you have the Adobe Flash Player plugin installed in your browser, you can verify below whether you've done your mental arithmetic properly - or you can also just lean back and let the software calculate the results :-).
Click on one of the piano keys with your left mouse button to add the respective pitch to the set, click again to remove it. By the way: »Alles löschen« means »Clear all«!
