(Dujon) The -34°C is rather mild for Jakutsk in Dec/Jan. The mean is -43°C. There is no wind, or snowfall, but the ground is snow-covered from what fell in Oct/Nov, typically about a foot. The only weather is fog, which can last for a week or more with temperatures down to -51°C, the lowest I've seen in 4 yrs daily monitoring. The short summer is like that of central France and it hardly ever rains. I bet they make the most of it. There is an even colder place, Ojmjakon, where the January mean is -50°C with no weather at all, just brief sunshine while the sun crawls shyly above the horizon for a few hours. Young kids are not allowed out of it goes below -45 because the cold air can damage their lungs. If you were so daft as to put the mouthpiece of a brass instrument to your lips in that degree of cold it would blow more than two semitones flat, the least of your worries, I'd say. Perhaps there's a special short Russian trombone.
What's the science behind that then, Rosie? I would have expected extreme cold weather to reduce the size of the instrument, thus shortening the column of air one needs to vibrate. I would expect this effect to sharpen the instrument.
(Phil) The instrument does get a tiny bit shorter (about 2 mm at -50°C) but the overwhelming effect is the reduction in the speed of sound as the temperature goes down. Since there is a standing wave in the instrument the lower speed causes it to take longer to go down and up the instrument, thus lowering the frequency and therefore the pitch. In effect the instrument becomes longer as far as the standing wave sees it. Of course the player's breath warms it up quite a bit, about halfway beteen ambient and body temperature. Even allowing for this (which I didn't in my original posting), the adjustment is about one inch on the tuning slide for 20 degrees and this is just a bit more than is usually available. So if you're playing outside at 0°C all you could do would be to play "short", as they say. Fortunately I don't do marching bands or Sally Army stuff.
(Darren) That's correct. The whole instrument would be flat and it wouldn't sound wrong but any other instrument accompanying it would have to tune down a bit. Rather difficult with a piano. One way round it would be to have a small bleed of a lighter gas into the air the organ uses. You could use hydrogen, helium, neon, methane, ammonia or hydrogen fluoride. Perhaps I should patent this lunacy.
Wouldn't some of those risk producing the Amazing Exploding Organ? That puts me in mind of the Large Hot Pipe Organ which produces sound by exploding a propane/air mix in its pipes.
(Darren) It's blown itself to pieces and taken the website with it. I drew a blank with your link, alas. Helium would be safe enough and it's much cheaper than it used to be. It would be amusing to use sulphur hexafluoride, totally inert and non-toxic. It would lower the pitch by over an octave. I think I'd better shut up now.
My curiosity is partially because I'm playing carols at the village Christmas tree tomorrow evening with the local brass band. Getting 40 or so of us in tune may be interesting if we get a cold evening.
(Phil) If all the brass is out of tune by the same amount it won't matter. I suspect there will be enough left on the tuning slide to accomodate an average cold evening.
[Darren] I'm currently reviving my interest in playing B-flat cornet, having not really played it for nearly 3 years. [Rosie] That was what I thought. I might have to get a bit of practice in tonight, and give the old horn a good clean.
(Phil) I hope your lip won't have gone. I wouldn't dare go three days without blowing a few raspberrires down my nine-foot tube. Brass is a treadmill; constant practice just to stand still.
[Rosie] I was jolly chuffed with my performance as 2nd Cornet. Good news was that my part had nothing above more than an octave above Middle C, so my lip survived with no problems. They've now gone and asked me to join them on Sunday morning to play at various points around the village, traditionally accompanied by hip-flasks. Mr Phil has given permissions, so it looks like I might end up signing up to join permanently in the New Year.
(Phil) Shouldn't be too bad. One is expected to get that note on the 'bone (not too often) but the worst thing about it is reading it, being all in bass clef. The rule is that if it's in the stratosphere and on a space it's a C, otherwise it's a B (usually Bb). If it's a D the composer/arranger is not a trombone player. These high notes are far better played by trumpets and cornets anyway. Power to your embouchure. :-)
(Darren) Although leger lines are part and parcel of trombone playing (especially 1st and 2nd trombones) I'm very glad they don't go into Tenor Clef which to me would make it unreadable instead of merely difficult. Treble Clef is never used because most 'bonists can't read that either unless like me they're also piano players.
[Raak] It happens often enough for you to realise that you shouldn't get caught out by it, if that makes any sense. Depends on what key you're in, you see...
How do you get rid of the smell of a stink bomb? Some little f*cker put one under my front door mat while I was out shopping tonight. I'd like to rub it all over his best Nikes.
Hope Rosie doesn't mind me quoting this in here [picked up from Limerick Game] .. "(Chalky) Cheers. The busiest thing I am doing at this time of the year is firing off apologetic letters to all those who sent a Christmas card to my late Mum. Oh, the sins of omission." [Rosie] How soon one forgets! This is quite a poignant time for you in some respects, 'though I suspect you will end up doing exactly as you wish, according to your personal bodyclock, and having a rip-roaring time. Have you been deluged by kindly invites so you're 'not on your own at Christmas'?
I've just stirred 2kg of chocolate truffle mix into a glossy, brandy-infused bowlful of indulgence, now it has to cool off to almost-solid in the utility room (luckily it's bloody cold in there) so I can scoop it out with a melon-baller into about 400 truffles. Yum. And I'm still in my pyjamas :o). I think I'll have my mum and a friend coming for xmas. The friend was coming over from France to stay between christmas and new year anyway, but brought forward his trip because of a funeral, so I've insisted he should come here. [Rosie] The point I'm getting around to is, the prospect of having someone new and 'not family' at christmas is lovely. If someone offers you an invitation, accept it. They may need to invite you as much as you feel like accepting it. Sometimes, when you dilute a family, it gets better.
[pen] .. the inside of your salsa shoe is a more effective as a wasp killer than the minus degree temperatures outside? What does this say about your shoe?
(Chalky) No invites. I think friends know me well enough not to do that though I wouldn't mind going to my various cousins in N London, an agreeable lot, but maybe they too know that I won't mind being on my own. Or perhaps they're having a tremendous row about what to do at Christmas. You never know. :-) (pen) If a Morniverser turned up on the doorstep they'd be welcomed with open arms. It would be a most original way to spend Christmas. Re - dead wasp. It means you've got hot feet. Of course this should be interpreted metaphorically and with the kindest possible intentions. :-)
Christmas office do last night *groogh*. About 50% of the company stayed at my house last night, and another 12%, not wanting to be left out, appeared on the doorstep for breakfast this morning.
Something Needs to be Done about high-resolution screens. This laptop has a 1900 by 1200 screen 13 inches wide, but of course all the fonts are exactly the same size in pixels as they were when 640 by 480 was the largest screen you could have. The first thing I had to do to make the laptop usable was to set all the options to get text in a readable size and a mouse pointer I can see. There needs to be a switch at some point from specifying font size in pixels to specifying it in millimetres. (Points won't do, having for better or worse been tied to pixels when a pixel was about the same as a point, and having shrunk along with them. There are probably people nowadays who think that a typographical "point" means a point of light on a screen.) The display would inform the computer of its physical size, and all GUI elements would have their sizes specified in physical distances instead of pixels.
[pen] We had our works do last Tuesday night. A few of us managed to struggle in the next day... I went home after an hour. That was Very Naughty Indeed.
[rab] you didn't plan to work a whole day? V.N.I. indeed. There's no let-up here... besides which, I got a promotion this morning and am now account Manager :oD. Despite that, I still feel hungover, and very, very tired. There's a queue stalling at the printer right now, and it's making me cry, that's how tired and emotional I am!
I'm working all day tomorrow... bliss! I might take my laundry to dry on the office radiators as I don't have to have the heating on at home and there's no-one else in. By the way, snow is forecast for the south-east in the middle of next week :o)
Not that there's much to do. I've been training for the past week, so it's taken me till now to sift through my emails! And I think we're all finishing about 1pm, for some drinks. I'd better get food as well, as I haven't had breakfast and the canteen is way too busy for me to be bothered to go up there.
[snorgle] You have a canteen? Wow. Even though I have the best job in the world, we still have to bring our own lunch in or head out in the car at lunch time to buy it. Today I have pasta and tomatoes left over from last night, mircowaved :oP
