What makes music sound funky? What makes it sound thrilling, sad, offbeat or downright strange? What makes you hum along, before you even know what notes come next?

Music is hardwired in your brain. I spoke about all this with Roger Dumas. Dumas is a neuromusicologist and brain-audio innovator, with a long, and interesting career. Having introduced Janet Jackson, Prince and other hip artists to the Moog synthesizer, Roger took up research work at the University of Minnesota’s Brain Sciences Center. These days, Dumas is working on behavioral and neuroimaging, and the validation of a musical chill-identifying algorithm.

Then, there’s the sounds of silence — formerly sound-rich ecosystems, bursting with bird songs and insect buzz, that don’t resonate like they used to.

Earth’s oceans, filled with sound wave artists of all sizes, have fallen silent too.

Or, maybe it’s human noise that’s drowning out the sounds of nature, along with all the chatter and noise in our head.

People need to quiet down, focus and listen harder. They need to come to their auditory senses. Bernie Krause and Hildegard Westerkamp think so. Bernie Krause is a soundscape ecologist based in northern California. Armed with various recording devices, Krause — the originator of the acoustic niche and biophony concepts — has captured the sounds and songs of creatures large and small, above and below ground, and inside trees.

Hildegard Westerkamp is a Vancouver-based composer, radio artist and sound ecologist, and an alumnus of something called the World Soundscape Project. Westerkamp’s soundscape installations and small group soundwalks, down Vancouver streets, are renowned.
