Composition in a Live Coding Environment

by Jordan Berg

Live coding in an interesting practice that I first attempted this semester as a member of the ICE Integra Contemporary Electroacoustics Ensemble at the University of Lethbridge. I am a composition major in my final year and have participated in the last two ICE concerts primarily as a percussionist and improviser. This fall I was introduced to live coding and learned the basics over the course of the semester in order to perform what I had absorbed live in our final concert on December 3, 2018 at the Zoo.

Live coding requires a musician to type lines of computer code into an interface to produce sound. It is not just as simple as pitch, dynamic, rhythm and duration – all of these parameters are controlled by the code as well as reverb, modulation, placement within the stereo field, repetition and more. There are so many aspects the performer can control that it would (and does) fill a small book and continues to be developed by musicians and programmers. It is possible that a live coder could perform Beethoven’s Fifth Symphony (with difficulty), but due to the nature of the constant looping that is essential to this practice, the style that has developed is different from the linear world of classical and popular music (although not necessarily). My first attempt at this was to figure out how to code ‘Walk This Way’ by Aerosmith using strange sounds for the first assignment. I felt that I was successful in this and for my second attempt I tried for something more ambitious. This attempt failed miserably because the complexity of having to type in pre-planned pitches, rhythmic groupings, and layers of commands in a live environment can come crashing down if the performer misses something as simple as a single character. I felt that the more successful attempts by my classmates relied less on pre-planning and more on aleatory. The understanding of the code and a rough idea in advance lets a performer engage in the live sculpting of sound rather than a frantic attempt to type pre-existing pages of numbers and characters into a computer under low light with many people watching. The latter seems to guarantee failure.

As a composer, I have always found it difficult to reconcile the relationship between being hyper-controlling on a measure-to-measure basis and letting things form over time without judging them instantly. Part of the problem is the ability to immediately listen to what I’ve composed on my computer at the touch of a button. I have no idea what makes me decide why I think something sounds good and something else doesn’t. I compose something based upon a concept and then I listen to it and hope that it sounds acceptable. If it doesn’t, I delete it instantly. I’ve been told constantly by my composition professors that I need to allow my music to travel into zones that I might not be comfortable with and I’ve never been sure how to accomplish this. My experience with live coding has taught me to value the randomness of initiating a concept and then allowing it to form and develop on its own before I decide to nudge it in a different direction. I realize now that the same is true on the manuscript page. Sometimes you need to allow an idea to come to fruition based on the parameters that you set into motion earlier rather than to judge the perceived acceptance of the results on a note-to-note or measure-to-measure basis.
