I recently gave a talk at TedXTokyo 2014 about a musical device I built with the aim of giving other people the chance to hear the world as musically as I do. To date, around fifty people have tried my mobile composing inspiration rig with me – mostly with very enthusiastic responses afterwards, and in the more musical/auditory types there’s also a degree of joyful disorientation.

Some of the background to what I think is going on: Around twenty years ago, psychology professor Diana Deutsch discovered what she called the Speech to Song illusion. Essentially, a spoken phrase repeated often enough starts to take on musical qualities. There’s a great Radiolab episode which explains the phenomenon.

For me, I don’t require repetition in order to hear spoken phrases as musical. Speech is intrinsically musical for me, and so is the rest of the world – from cars passing to people typing. I really wanted to share my experience as I find it very beautiful.

 

STORY TIME!

It was the day after winning a prize at MusicTechFest’s Boston Hackathon event, which I took part in and filmed for the BBC. I was sharing a small apartment with a bunch of other music obsessives.  The day before I left, instead of packing neatly as normal I optimistically chucked everything I could see into my case and hoped for the best.

The idea of adjusting auditory experience or adding a ‘Glitch’ to reality – at least in aural terms – is not a new process.  But glitching with modern tech sounded like a great way to reveal the music I hear all the time – plus I wanted to add a more musical classical compositional element to the practice.

Sean Manton and CJ Carr (who was familiar with glitching) were two other music hackers I met at the Hackathon. They were instrumental in my sleep-deprived electronic inspiration.

So, grabbing my iPad and headphone splitters,  I built the first iteration of a device that messed with the ambient sound in the room in real time in a pleasurable manner. Raw audio is changed in real-time and enhanced with sound effects, and crucially, I added basic musical elements and phrases that would play simultaneously. A while later, I got the thing working in a way I liked and emerged from my room, eager to try it on other musical / technical people. My ideal system would allow for me to sing and play melody and harmony but I was nowhere near doing that yet.

So, extra headphones bought, splitter in,  time to try my rudimentary iPad device on CJ and Sean in a quiet teahouse. It was so much fun! The sounds of tea being made, the door opening, teaspoons hitting cups, amplified and enhanced by repetition! Those sounds were unexpected, made musical and wonderfully tingly. I sang along to the notes in the cafe to accentuate them. The staff at the teahouse got interested, all they could hear was us singing and hitting teaspoons and laughing. So we asked if they wanted to try it then wired them in to see their response – they liked it – a lot.

 

Going mobile was more interesting – we were physically connected by our headphone cables, so it took a while to maneuver through the door but together we emerged, wired up out into the wild. And, once our headphones were in, we pretty much stayed ‘glitched in’ for at least 5 hours straight. I could hear the music I normally hear but amplified! Wow! I sang in joyous harmony with the world for my cohorts, who joyously joined in. An ear-opening experience indeed, and I expect we were a strange sight, connected together by cables, singing and swaying – especially as only we could hear the glorious harmonic results of our musical musings.

What followed: glitching around a bookshop, glitching through a delicious dinner at a noodle restaurant until we got chucked out at closing time – and (my favourite) glitching on public transport all over Boston. Some time during the evening, I added a recorded drum loop to the experience – an albeit low-tech but incredibly effective way to turn the world into a very funky soundtrack – rhythm along with harmony generated by reality transcended a run-of-the-mill walk through a city, making it a musical recital!

Now, without our headphones in, the world seemed dry and desolate. And, after trying this on six other people with the persuasive line ‘Hey, you wanna do some digital drugs, guys?’ to gratifying results, it didn’t take long for us to ascertain this was indeed a pleasurable and slightly psychedelic auditory experience – not only as a participant, but also as a listener. The three of us decided to take modern glitching further with a bit more technological clout.

A quick stop on the way back to the hacker apartment meant we now had extra kit. And, by 0100, Sean had plugged his Raspberry Pi computer into the TV – programming on the Pi with PureData. We made some tea and ate bread with the most delicious honey (the honey was in Bb major 6th) and kept working. By then it was 0300 and my taxi was due to arrive at 0615, we only had a few hours left!

We all wanted to add fine-grain control to this strange and wonderful auditory experience. CJ had brought his FM transmitter and binaural microphone/headphones and we plugged everything into my Mac.   I wanted to do more than just sing the city, I wanted to play it too. That meant configuring something that could take multiple inputs – MIDI and Audio at the same time.

Finally at 0400, and full of incredible quantities of tea, bread and honey, we were now running a glitching instance on Ableton Live, with a binaural microphone / headphone setup and my iRig Keys midi controller hooked up. I started building musical stems right then and there.

The latest version has more than just repetition, my new glitching device can harmonise and play with the world in a much deeper way – and I walk around a city first to get what key its in and compose something beautiful that goes with the natural sounds around me. Then I load those sounds up – I can then trigger them when I hear something in the right key, so a motorbike going past in B flat will mean I trigger my ‘B flat, traffic’ piano composition. The main problem is that the laptop gets really hot, also I’m covered in wires so it looks a little strange.

And this is what glitching sounds like – some of these examples have music in, others don’t.

The tech is still very much hacked together, but there’s more documented in the talk.

 

WHAT HAPPENS NEXT?

CJ, Sean and I are all enthusiastic about sharing the joys of glitching – and we’re all working on versions of glitching devices. We’re hoping to create a resource online for anyone interested to play with the idea in their own way.  I’m going to list everything I use in my hacked-together inelegant solution in another post.

I want an app that does this! I want to create a glitchpad! Beautiful musical stems that trigger automatically when friends walk through that city with this app! I want to be invited to perform ‘glitching’ concerts in cities around the world!
