REPARAMETRIZATION 1 is a piece for Flute and Real-time electronic manipulation written in 2007.  It is the first in a series of works where some parameter or parameters of an interactive performance system changes over time turing the electronic response to live performer input into a musical instrument in it's own rite.  The computer programs are often controlled by engineers, however, they are mostly designed to allow performers to practicy by themselves. 

In this piece, the flutist manipulates two pedals to change two parameters of the electronic manipulation. At the beginning and end, they control the amount of their sound that goes into an effect where their sound is "chopped up" by an automatic process as well as the speed at which the sound is chopped up.  In the middle of the piece, they control the amount of their sound that goes into a delay effect and the delay time respectively.  

As this was the first such piece I had created, I mostly served as the engineer during the performances so was not as concerned about usablity.  In more recent years, I have updated many of these pieces to make the experience of setting up and practicing with these patches more intuitive for the users.  

To remedy some of these issues, I created a re-design in 2020 that created a user experience.

Another way that the performer interacts with this system is through the written score.  The score not only provides notes, dynaics, and articulations as a normal piece of music woud, but also instructs the performer on how to manipulate the pedals.  In the original score, I used two extra staff lines with circles and dotted lines to represent the position of each pedal.  

In the revised score, the pedal markings are modeled after already established crescendo and decrescendo markings, leveraging the performers mental model of how gradual increases or decreases in volume are marked in music.  It is also marked much more boldly so is easier to read.
