Physical instantiation of a location-based ringtone

Music Score Bench(picture taken by myself in lyon this morning)

I don't imply it it's really what this title want to express but: Location-based: because it's something contextualized and inscribed in a place. Ringtone: what is represented here is a short melody so, by analogy, it can be thought as a ringtone (although the person who drew it is not that literate in music annotation). In the end, this can be described as a "physical instantiation of a location-based ringtone", no device needed!
