Nature-Symphony 30
— Mother Nature telling springtime melancholy not to be so silly!
Basic details
-
Instrumentation — Part of field recording of sextet of metal wind chimes, used as 2 layers, and part of a long recording of a Dartmoor birds' dawn chorus.
-
Original field recording location / date:
- Metal chimes: 19 March 2014, high up on north side of Teign Gorge, Drewsteignton, Devon, UK.
- Dawn chorus recording: 1 June 2019, north-west flank of Bellever Tor, near Postbridge, Dartmoor, Devon, UK.
-
Processing — The layers were processed as follows:
- Layer 1 (metal chimes): half-speed, thus an octave below original; 'back of cathedral' acoustic
- Layer 2 (ditto): speed reduction to make it an octave plus a fourth below original; moderate 'back of cathedral' acoustic (also two additional layers just reinforce the final climax, being higher-pitched — slowed to reduce pitch by just a fourth);
- Layer 3 (the dawn chorus): no speed or pitch change; a modest reverb added, to help integrate the sound properly in the mix.
I give some more specifics about the recordings, chimes used, and the subsequent processing, on my Freesound page for the work.

Distinguishing features — Both the metal chimes layers contain the same chimes ensemble, so they should sound just the same apart from Layer 2 being lower-pitched — right? — Well, actually no, for a specific reason. As we lower the pitch of the recording of these chimes, there come points beyond which, within our perception, a particular harmonic of a tube will no longer function as a harmonic, but will be perceived instead as the fundamental. Then, what had been perceived as the harmonic before, if it's noticed at all, gets experienced as an undertone. Differently-pitched tubes will have their own individual points at which a specific harmonic becomes perceived as the primary 'singing' tone.
That means that the perceived intervals between notes are different when heard in different pitch ranges. For this reason, the top layer here has a fairly melancholic sound — indeed a rather 'twisted' sort of melancholy, thanks to the presence of the Gregorian chimes —, which one would expect to largely counter the melancholy effect of the Olympos chimes — yet Layer 2, being a fourth lower, has a significantly more positive sound, with little of the melancholy. The two layers interacting still sound fairly melancholy overall, but with changes of mood according to which layer has dominance at each point.
Towards the end, a big climax in Layer 2 brings forth a great surge of positive energy, throwing aside all doubts and equivocations. I reinforced that, using a copy of that climax, made direct from the original recording and reduced in speed only enough for pitch to be a fourth lower than original, which is higher than Layer 1 or 2 and so adds more brilliance and sparkle to the climax.
The dawn chorus recording starts extremely quietly, much of it initially being masked by the chimes, but as it develops and more birds are singing, some quite nearby, one's attention is progressively focused more on that dawn chorus and less on all that melancholy stuff.
I was going to copy one of a choice of close-encounter cuckoo events to add into the actual ending, but by one great fluke, I found that 'Mother Nature' had actually done it for me, and perfectly, so I had no cause to add anything there!
