an inter-galactic soundwalk in 3D audio

Experience the famous orchestral suite “The Planets” by Gustav Holst, played by the Munich Philharmonic Orchestra, as an interactive audio walk in a park near you, increasingly all over the world. All you need is a smartphone and headphones.

In seven parts, the seven planets Mars, Venus, Mercury, Jupiter, Saturn, Uranus and Neptune are characterized musically. In our app you can find these planets distributed in the park and visit them.

Immerse yourself in an intense musical experience of the planets. You can freely move around and explore the immersive sound field of the orchestra.


Get on a shuttle that will take you through space.


You navigate the shuttle with your feet, walking.

Play an auditory treasure hunt that takes you from planet to planet via binaural 3D audio. Listen to the direction from which you hear speech and music and find your destination.

Float on the music, through space, in the park near you.


Experience the app in one of 22 Munich parks, but also elsewhere in the world.
