Wheeled suitcases are favored by travelers for their maneuverability.

But during Octoberfest season, a Munich Airport (MUC) installation is proving that wheeled suitcases can also make music.

Sponsored by German brewery Paulaner, the SoundTrack installation between Terminals 1 and 2 at Munich Airport is a walkable track made of acrylic glass with milled grooves.

If a traveler walks along the track with their wheeled suitcase and sets their stride to a strip of lights, the tones made by the wheels on the track will ‘play’ the melody of the well-known Oktoberfest song Ein Prosit der Gemütlichkeit. During Oktoberfest, whenever the tune is heard, festival participants are supposed to raise their mugs.

The installation works a bit like a record player, with the wheels of the suitcase serving as the ‘needle’ that reads the grooves on the record.
