What does a forest stream sound like when slowed down, especially when the trickles and bubbles become unusual rhythmic structures?
This is a Sound Art piece and developed from crossfading four different sound sources together. Some of them have been slowed down by recording them onto magnetic tape on an elderly Ferrograph reel-to-reel machine, to as much as 1/64th of their normal speed to reveal the hidden and unusual sounds present. I recorded the source material along the Ober Water forest stream near Brockenhurst.
The piece starts with the stream at normal speed and then bit by bit, it gets progressively slower, and interesting rhythms start to emerge.
The dawn chorus of birdsong is the natural world’s most impressive and renowned ‘concert’. It sounds beautiful to us, but to the birds it’s simply a way to for rival males to resolve territorial conflicts. Basically, the louder and stronger your song and the more time you spend singing it, the better territory you can claim and the higher the chance of a female choosing to mate with you.
Experts contend that birds sing in the mornings because at this time, their sound carries further due to the lack of general noise and also the density of the air at that time of day.
The first birds to sing are often blackbirds, robins and wrens. Apparently birds with larger eyes start to sing earlier than those with smaller eyes. Larger eyes provide better light-gathering ability, so larger-eyed birds feel safe singing in the low, early dawn light because they find it easier to spot predators that might be attracted to their song.
Most of the dawn chorus comprises of males singing constantly repeating patterns of tones from elevated or conspicuous spots within their territory or breeding areas. Once the light levels start to rise, it’s often hunger that drives birds to stop singing and start looking for food instead.
