New App, AstroCantus, ‘Plays’ The Universe

AstroCantus is a mobile application that translates the celestial map into music.

In a nutshell, as stars, galaxies and nebulae cross the celestial meridian, they trigger notes, using an instrument and scale that you select.

While the app explores the ideas related to found music and generative music, the feature set is basic, making it less of a musical tool and more of an educational or entertainment app.
