Musical Signatures From Your iTunes Library
We rely on many ways of recognizing people, near at hand or from afar; faces, voices, walks, and even the scents from favorite colognes or perfumes help us greet friends, engage colleagues, and identify strangers.
I was in high school when I first noticed that everyone’s key chain made a distinct sound, one that served as a kind of audible calling card that could help recognize people. I started to try to guess who was walking to the front door by learning the unique combinations of sounds — clinking and tinkling from metal keys, rattling and rubbing from ceramic and plastic tokens, and a myriad of other noises from the incredible miscellany people attach to their key rings and carry around with them through life — that announced each of my visitors friends. With a little practice, I could pick out the ten or fifteen people I spent the most time with based on listening to the sounds of key chains. Everyone else was someone I didn’t see often, which was a fine distinction to draw between when gauging how to answer the door.
There are many other audible cues to identity — from the closing of a car door, to the sound of foot steps, or cell phone ring tones — but the key chain is unique because it includes so many different elements: the number and size and materials of the keys, or the layering of different key rings and souveniers people attach to them. A key chain is a sort of impromptu ensemble of found instruments playing little bursts of free jazz like personalized fanfares for modern living.
The sound of someone’s key chain also changes over time, as they add or remove things, or rearrange them. That sound can even change in step with the way your relationship to that person changes. For example, if they buy a souvenier with you and put it on their keychain; or if you give them keys to your apartment. Each of these changes reflects shared experiences, and you can hear the difference in sound from one day to the next if you listen carefully.
And like those other ways of recognizing people I mentioned earlier, which all reach the level of being called signatures when they become truly distinctive, the sound of someone’s key chain serves a sort of audible signature.
Until now, the sound of a keychain was perhaps the only truly unique audible signature that was not part of our person to begin with (like the voice). Now that Jason Freeman has created the iTunes Signature Maker, we may have an audible signaure suitable for the digital realm. The iTunes Signature Maker scans your iTunes library, taking one or two second snippets of many files, and mixing these found bits of sound together into a short audio signature. You choose from a few parameters such as play count, total number of songs, and whether to include videos, and the signature maker produces a .WAV file.
I made an iTunes signature using Jason’s tool a few days ago. I’ve listened to it a few times. It certainly includes quite a few songs I’ve listened to often and can recognize from just a one-second snippet. Calligraphers and graphologists make much of a few handwritten letters on a page: music can say a great deal about someone’s moods, outlook, tastes, or even what moves their soul. I listen to a lot of music via radio, CD’s and even live that isn’t included in this. I’m not sure it represents me. I think it’s up to everyone else to decide that.
But what can you do with one? It’s not practical yet to attach it to email messages, like a conventional .sig. It might be a good way to bookend the mixes I make for friends and family. I can see having a lot of fun listening to a bunch of anonymous iTunes signatures from your friends to try and guess which one belongs to whom. There’s real potential for a useful but non-exhaustive answer to the inevitable question, “What kind of music do you like?” when you meet someone new. Along those lines, Jason may have kicked off a new fad in Internet dating; this is the perfect example of a unique token that can compress a great deal of meaning into a small (digital) package that doesn’t require meeting or talking to exchange. I can see the iTunes signature becoming a speed-dating requisite; bring your iTunes signature file with you on a flash drive or iPod shuffle, and listen or exchange as necessary.
At least the name is easy: what else would you call this besides a “musig”. Maybe an “iSig” or a “tunesig”.
Unique ring tones, door chimes, and start-up sounds are only the beginning. Combine musigs with the music genome project, and you could upload your signature to a clearinghouse online, and have it automatically compared for matches against other people’s musigs based on patterns and preferences. Have it find someone who likes reggae-influenced waltzes, or fado, or who listens to at least ten of the same artists you enjoy. Build a catalog of one musig every month for a year, and ask the engine to describe the change in your tastes. Add a musig to your Amazon wishlists for gift-giving, or even ask it to predict what you might like based on the songs in the file.
You can download my musig / iSig / tunesig / iTunes signature here; note that it’s nearly 8mb.
I’ll think I’ll try it again in a few months, to see how it changes.
