The Air You Breathe

Swiss chemist Renato Zenobi has been analysing the chemicals in the air we exhale. His findings suggest that the metabolites in our breath could help early medical diagnosis or catch sports cheats right on the starting line. Tenor John Potter explains the intimate relationship between the singing voice and the breath. And, writer William Bryant Logan reminds us that the air we breathe is not a thing or a place but the continual product of the breathing of all living things.

60 second idea
John Potter suggests that we should disable all forms of electronic music reproduction and storage and impound all scores of western art music. This would force a return to music as a living thing that has to be actively created, not simply passively absorbed and taken for granted. Shops and restaurants would be free of background music, people would have to talk at parties, and the experience of music would be live, sociable and special. Obliging musicians to recreate the Western canon from memory would be a wonderful challenge and put it on an equal footing with other, equally valuable, oral musics from all over the planet.
