The Foghorn Requiem

Foghorns have been a part of maritime history since the 19th century, providing much needed safety during inclement weather to mariners out at sea. Over time, their relevance has slowly reduced, with advanced navigational aids taking over the task of keeping ships and sailors safe.

The sounds of the foghorns are slowly dying out. Artists [Joshua Portway] and [Lise Autogena] put together the Foghorn Requiem, a project which culminated on June 22nd 2013, with an armada of more than 50 ships gathered on the North Sea to perform an ambitious musical score, marking the disappearance of the sound of the foghorn from the UK’s coastal landscape.

The artists tried capturing this quality of the foghorn, with help from composer [Orlando Gough] who created a special score for the performance. It brought together three Brass Bands – the Felling Band, the Westoe Band and the NASUWT Riverside Band, almost 50 ships at sea and the Souter Lighthouse Foghorn to play the score.

Each of the more than 50 vessels were outfitted with a custom built, tunable foghorn, actuated by a controller box consisting of a TI Launchpad with GPS, RTC, Xbee radio and relay modules. Because of the great distances between the ships and the audience on land, the devices needed to compensate for their relative position and adjust the time that they play the foghorn to offset for travel time of the sound. Each controller had its specific score saved on on-board storage, with all controllers synchronized to a common real time clock.

Marine radios were used to communicate with all the ships, informing them when to turn on the controllers, about 10 minutes from the start of the performance. Each device then used its GPS position to calculate its distance from the pre-programmed audience location, and computed how many seconds ahead it had to play its horn for the sound to be heard in time on the shore. The controllers then waited for a pre-programmed time to start playing their individual foghorn notes. The cool thing about the idea was that no communication was required – it was all based on time. Check out the video of the making of the Foghorn Requiem after the break, and here’s a link to the audio track of the final performance.

This is a slightly different approach compared to the Super Massive Musical Instrument that we posted about earlier.

  1. Okay. It is a very long video but definitely worth watching the whole thing when you have the time.
    So, jump in at around the 19 minute mark you wont have to wait.
    And there is a nice surprise around the 21 minute mark. ;)
    I really thought this was clever, and it sounds great!
    Awesome sauce all around.

  2. As an ex-trumpet-player, I’m a bit snobbish about music. I can see how this was quite the feat to pull off, getting the sound from the ship horns to arrive on land at the right time, but damn is it out of tune at the beginning. It was very hard to listen to.

  3. Artist
    art·ist – /ˈärdəst/
    noun
    1) A person who can talk beyond the maximum believable amount of time about a thing containing a minimum amount of content.
    2) A person with a talent to explain, at length, the “importance” of something with no import in an effort to gather believers

    1. It’s not just artists. Almost everyone here including myself does the same thing.
      Yes, it was basically a documentary.
      I’m not sure I understand point 2. “no import in” “believers”
      I *sigh* kind of agree with aklsdjfkj on this.
      Tell us what was so easy or whatever. Explanation please.

    2. Wow. This must be the state of spirit those folks were in when they set fire to the Library of Alexandria [1]

      Please. Keep to the things you really care about and do Good Things. Let others do Good Things the way they care about. Life can be nice. Cheer up.

  4. I want some foghorns to use in my burglar deterrent system. One in each room should do it, and the ones in the kids’ bedrooms can double as wakeup alarms for particularly slow days. If I put them under the beds, they can also serve as monster deterrents (but activated by 𝘮𝘦, not the kids!).
