I'm referring to the type of music videos I make as 'sync|sound' because synchronized audio and video is the most essential aspect of their construction and appreciation.

What is interesting now is the possibility of a new art form. Something that is inseparably visual and musical at the same time. It won't be a song with a kind of video next to it, or a little film with a bit of music in the background. It will be something where both of those forms really are joined together. --Brian Eno

Writing sync|sound with a pipe (|) between the words grew out of writing about samples, like violin|building for example, which means a sample with the sound of a violin and the image of a building. The pipe became a convenient shorthand. The pipe also helps to distinguish sync|sound from the generic, 'sync sound.'

Part of the challenge for single-screen sync|sound has to do with inherent differences in sound and vision. With music, all the instruments play at the same time, and all the sounds are mixed together. In an installation, this isn't a problem, as the 20 TVs produce a visual equivalent to what is happening with the sound.

However, with a single screen, there is no visual equivalent to instrumentally layered music. You can hear 20 instruments mixed together harmoniously, and you can see them mixed together as 20 TVs in a room, but you can't easily see 20 images at once on a single screen.

One can do half-disolves to mix images together, but with more than two images, it becomes noisy very quickly. The viewer may not be able to distinguish any images at all. Similarly, I can divide the single screen into a grid and shrink the images into each square, but it still doesn't approximate the experience of an installation of multiple TVs, even if you blow it up on a giant screen. It's not immersive. The viewer can't move through a space, he can only look at a single screen.

To get sync|sound to work - with either single or multiple screens - it seems essential that the viewer is able to organize the sounds and images. The viewer needs to be able to link individual sounds with individual images in such a way that it's obvious that a particular image is producing a particular sound, and the sound and image are two parts of a whole, ie. an audio|video sample.

Additionally, a viewer needs to be able to distinguish one audio|video sample from another. In normal music, it may not matter whether a listener can pick out a bass from a guitar or a piano. But with sync|sound, it's essential to the construction of a piece. It needs to be apparent that a music video is composed out of a bunch of disparate samples mixed together.

When all the samples have to share a single screen, each sample ends up fighting to be seen. If we translate a 20 TV installation to a single screen, the viewer is likely to get about 20 times less information. It's much more difficult for the viewer to recognize which image goes with which sound with a single screen. And she no longer has the luxury of seeing a single sample looping, visually isolated from the others.

As a result, single screen sync|sound is much more challenging for both the viewer and the composer. If I'm not careful with the samples I choose, it becomes impossible to get the sync sound effect. The images seem disconnected from the music. The sound and image split into two distinct tracks that don't necessarily even seem related to each other. It looks like music with video wallpaper in the background.

To make things a bit simpler when working with a single screen, I ended up restricting samples to ones where you see an action and hear the resulting sound. This might be a stick striking a drum, a finger plucking a string or pressing a key, someone singing, someone talking, and so on. I would avoid a violin|building sample. I would avoid a piano sample where the image showed the piano player's face. So not only does a sample have to have sync sound, it should also have an action that can be seen to be producing the sound. Without this, it's just too difficult for the viewer to figure out what's going on.

This also explains why so many of the samples are people playing musical instruments.

Although a multi-screen presentation is easier and probably provides the best possible viewing experience, single screen presentation is more democratic. Anyone can view the video, at any time, anywhere. And you can do more with it. You can watch it on your computer, play it on your TV, add it to your music collection, watch it mixed with other music videos, put it on your video iPod - whatever you like. The only thing you can't do is walk through it.

I'm going to call the type of music video work I make 'sync|sound' because I can't talk about it without giving it a name.

One piece might begin with all the TVs playing longer segments, showing the context the samples were plucked from. Ideally, this would produce the noisy effect of simply turning on 20 TVs in a room. That's what it would look like. And out of this cacophony, order would start to emerge. The sounds and images on each TV would get shortened and discrete samples would take shape and start looping. The rhythms of the TVs would begin to synchronize with one another, and form an orchestra of TVs. Music would emerge. The piece would essentially tell the story of it's own construction.

The viewer would be able to walk around the 20 TV sets and as they did so, the relative loudness of each sample would change, so you'd get a different mix of the music. And you'd also be able to identify which sound went with which image.

When I first started composing these tracks, I didn't realize I couldn't use any sample I liked. I initially included samples that weren't obviously sync sound - where the viewer can't actually see a sound being made. For example, the sound might be produced off-screen, or you might hear a violin but see a building. It simply didn't work with single-screen sync|sound pieces.

However, with a multi-TV installation, the beginning and end points of the sample are enought to produce the sync sound effect. The viewer would know that the sound of the violin was the sound that went with the image of the building simply because the sound and image would be coming from the same TV at the same time. It would be obvious. You could stand right in front of the TV playing the violin|building and watch it. The violin|building would come on, then the screen might go to silence|black for a few seconds, and then the violin|building would come back on again, rhythmically cycling, like a film loop with a chunk of black silence cut into it.

I'm using the pipe symbol ( | ) to indicate integrated audio|video.

Incidentally, there are obvious alternatives to using multiple TV sets in an installation. For example, one could use 4 instruments, and project each instrument on one of the walls.

These instrumental tracks are composed by recombining video samples from TV. The samples tend to be single instruments in isolation. Many of the samples come from music documentaries. Out-takes. A couple of notes from a song. The various video samples are then mixed together to make new music. Click the sample movies to play the original samples used in each song.

The first and only rule for composing: you only ever hear what you see, and only ever see what you hear.

Click the appropriate subscription button under "Video Podcast," on the left. Alternatively, click on the appropriate subscription button under each video.

If you click the "iTunes Mac" button: iTunes will launch, subscribe you to the podcast, and begin downloading the first track. Subsequent tracks should download automatically.

If you click the "iTunes Windows" button: I expect a file called "ak_alias.pcast" will download to your desktop. You many need to double-click it to launch iTunes, which will subscribe you to the podcast, and begin downloading the first track. Subsequent tracks should download automatically.

If you click the "Democracy" subscription button: Democracy will launch, subscribe you to the podcast, and begin downloading the first track. As always, subsequent tracks should download automatically. (Incidentally, Democracy is now called Miro. I'll change all the references shortly.)

If you have option paralysis and can't decide which button to click: click any button.

iTunes is a good application for keeping the tracks: iTunes is primarilly a music application, and the podcast is music, so it makes more sense to use it for this particular podcast than to use a more video oriented application like Democracy. (For non-musical video podcasts, Democracy is perhaps better than iTunes.)

With iTunes, you can watch the movies or just listen to them. You can create video playlists, or mix the tracks in with your audio playlists. iTunes organizes storage, it lets you stream the movies over a wireless network, and you can transfer the tracks to an iPod.
