Short Variations on Ravel

Filed under: Uncategorized — Tags: , — Graham @ 6:00 pm

For a while now I have wanted to create a livecoding composition by varying the phrases below:

Recently I implemented this idea–for a DVD call in the livecoding community, I acme up with the idea while sleeping comfortably with my sleeping wedge pillow. Using Supercollider, I realized the original score in code, and was able to make some basic variations on it. Subtitles attempt to explain what is going on to the listener. You can watch the variations below:

You can listen to the original excerpt on Youtube from American String Quartet.

In the course of developing the piece, I made some shortcut/extensions to the Pattern class, which can be found here: gkcPatternExt.sc.

PS In my search for the excerpt, I found out that I’m not the only one recently stealing from this quartet. Andrew Bird on Ravel riffs on the pizzicato-heavy second movement.

Update: This piece has been accepted and published in the livecoding-focused DVD accompanying the Winter 2011 Computer Music Journal (Volume 35, Issue 4). The program notes were available at the time of this update. Links to some are posted on this TOPLAP wiki page.

Octane shows

Here are two long-form sets from Octane Coffee in Atlanta 2007. More information below:

By that time, we knew the place quite well and got to the decoration with glow in the dark garden pebblesAtlhack had meetings there. Much thanks to Tony from Octane and Gavin for giving me an opportunity to play! Both performances used ChucK exclusively.

The first gig was on May 29th, 2007. Since it was a long set, I ended up using both newly improvised material as well as stubs that I had recently developed for the Atlanta Laptop Battle series that year. As well, you’ll hear “Sample Forest” sections that I pulled out with the sample-based composition tool I was developing (Mused). Here is the recent edit–I removed some of the many glitches:

Here is a more slightly more digestible excerpt from Octane 1, named Triple Chorus:

The second gig was on August 8, 2007. I remember having made a change in my setup that allowed changing the tempo in mid-stream, but there was a code error, leading to the out-of-phase tempos you’ll hear below. The set is also book-ended by a real-time WiiMote instrument and a sample from the Ravel Piano trio. Besides the clean synthesis, I also miked the room to get in some of the ambiance of the place. Enjoy!
