Journal tags: tuning



A few years back, Jessica got a ceiling fan for our living room. This might seem like a strange decision, considering we live in England. Most of the time, the problem in this country is that it’s too cold.

But then you get situations like this week, when the country experienced the hottest temperatures ever recorded. I was very, very grateful for that ceiling fan. It may not get used for most of the year, but on the occasions when it’s needed, it’s a godsend. And it’s going to get used more and more often, given the inexorable momentum of the climate emergency.

Even with the ceiling fan, it was still very hot in the living room. I keep my musical instruments in that room, and they all responded to the changing temperature. The strings on my mandolin, bouzouki, and guitar went looser in the heat. The tuning dropped by at least a semitone.

I tuned them back up, but then I had to be careful when the extreme heat ended and the temperature began to drop. The strings began to tighten accordingly. My instruments went up a semitone.

I was thinking about this connection between sound and temperature when I was tuning the instruments back down again.

The electronic tuner I use shows the current tone in relation to the desired note: G, D, A, E. If the string is currently producing a tone that’s lower than, say, A, the tuner displays the difference on its little screen as lines behind the ideal A position. If the string is producing a tone higher than A, the lines appear in front of the desired note.

What if we thought about temperature like this? Instead of weather apps showing the absolute temperature in degrees, what if they showed the relative distance from a predefined ideal? Then you could see at a glance whether it’s a little cooler than you’d like, or a little hotter than you’d like.

Perhaps an interface like that would let you see at a glance how out of the tune the current temperature is.
