Not very exciting just some loops that could be triggered. But think that you could spend some more time and do something that could be useful and in the end you can easily compile it into an APK to use and distribute to other devices.
It is for free and developed by Massachusetts Institute of Technology
Have not used it so do not know how far you can take it but guess you should be able to do an application for your music maybe even something interactable to release on the Playstore.
Would normally try it before posting but knowing myself and having fifty other projects and things to do it would not happen until months from now...
It does look like good even if you are not going to do something revolutionary and they are working on a second version that should be out in a month or two.
To go and download it and read what is possible:
Here is a small introduction video and there is a lot of tutorials available on YouTube.
In the end of the video he is talking about paid courses that you can take but it seems to me that is not the case anymore after MIT took over the project from Google so now all the tutorials are for free.
Cheers to you Massachusetts Institute of Technology.
