This sound technology area within the Canada Science And Technology Museum featured both artifacts and interactive displays. How we've listened to music has changed down through the years.
By the mid 1940s, radios could be smaller and placed on a counter or mantel.
And I'm sure many of us have had a walkman.
While most of us have some variation on its contemporary replacement.
Something of a historic treasure, though it looks quite utilitarian, is the first synthesizer, invented by Hugh Le Caine, a Canadian physicist and composer who worked for the National Research Council of Canada for many years, and who created the Electronic Sackbut.
It doesn't look like much, but every musician using a synthesizer today owes it to this device and its maker.
In an alcove off the entrance was a sound and light display. It is here that I end the series. The installation takes its inspiration from the aurora borealis, the Northern Lights, with changing, shimmering lights overhead. I hope you've enjoyed this visit to the museum.
