Moving in space and time: David Evans on The Sound Barrier!

The Sound Barrier for Sunday 19 March 2017

It was over 100 years ago that Einstein told us that space and time are relative to one another and that motion effects how time passes.

But what does this mean for music? Do things sound different when they speed up or slow down? Do they sound different when they move in a straight line or turn around a bend? If time and space are related to each other then what shape does time have? How do we perceive it when our position in space changes, and how does our position in time affect our memory of space?

This weekend on The Sound Barrier I'll be exploring these questions with two major pieces of music: an upcoming new release based on field recordings from Melbourne musician David Evans, and a far-roo-rarely heard work from seminal acousmatic composer Fran├žois Bayle.

David will be joining me live in the studio to talk about Suddenly Woken by the Sound of Silence, being released next week on Flaming Pines, where sounds from his journey on the Trans-Siberian Railway in 2015 are revisited and reimagined, and questions are explored about how sound changes with speed and motion and through the passage of time.

I will also be playing Fran├žois Bayle's La Forme du Temps est un Cercle ('The Form of Time is a Circle') from 1999-2001, which draws from the Pythagorean notion of the circularity of time, and which its composer describes as a work where, throughout its five major stages, 'the listening journey will have completed a trajectory, that of the time unit going towards its smallest texture, and perception gradually sharpening its assessment of image and form'.

I hope you can join me, this Sunday night on The Sound Barrier, which goes live to air, both on radio and online, at 10.00 PM (AEDT). You can tune in at 106.7 PBS on the Melbourne FM band or on PBS Digital Radio, or online via the website or the PBS app. The show will also be available here on the website, both to listen back to and to check out the details of the playlist, shortly after it has gone to air.
