Testing sensor system on a dancer – day 2

Testing sensor system on a dancer – day 2


I will test Eowave’s Eobody2 HF on a dancer.


I want to see if this system works with our project.


I will have the sensors control simple parameters.


After the first day we met I made some enhancements to the setup.

If anyone is interested, this is the current MaxMSP-patch.

I consider pitch, speed and volume as three essential parameters to investigate further as those are quite relevant parameters in traditional music.

In the first example, by turning her hand around the z-axis, the dancer would control the pitch and speed of a simple drum loop.

The reason why we chose not to separate pitch and speed was that after some intents with just controlling the speed we felt that excluding pitch was very unnatural, probably because they both reinforce each others effect and historically we are used to them being tied together (slow down a tape or a vinyl and the pitch will drop).

The original idea was that I would measure the distance between her hands to provoke this action, but we figured out that it would be easier to “fake” it by turning her hands while pulling them apart. I got this idea after an inspiring session with Alexander Refsum Jensenius who made it clear to me that to actually measure the distance between her hands was harder than I initially thought.

As you can see, we are starting to enjoy this. And the system is behaving exactly as expected.

Next, I made turning around the x-axis control the volume of the drum loop.

It is quite obvious that the dancer found this somehow more boring, but it had to be tested and I think we can get a use for it because the link between the movement and the music is so clear.

And again, the system is behaving exactly as expected.

In the next test, I combined the two above, so turning around the z-axis will change the speed and pitch and turning around the x-axis will change the volume of the drum loop.

This clip is notably longer since the dancer is now inspired to explore the possibilities further and we felt that we were ready do to a test performance.

I wanted to emulate that I was playing the drums since that is where we are going, so instead of the drum loop we used a loop from a solo performance I did almost a year ago.

I also wanted to challenge the dancer with some other parameters. This time she controls delay feedback and pitch. You can see the parameters in Ableton Live being modulated in the upper left corner.

I like this. Of course it gets boring after a while, but I would gladly make this a part of a performance.

If I were to play instead of the loop there would be an extremely direct interaction between the music and the dance: I would be playing with both what I hear and see the dancer do and she would be inspired by what I play and what she hear she is doing with the music.

I have now applied for some funding to buy the sensor system and develop a performance with this setup.

Even though this seem quite poor from an artistic point of view, I feel that we are on the right way to do something quite original and the possibilities of what this can bring are just starting to show.

More on this project when money comes around.

  1. This is very cool Jonas!

    Just a thought: Would it be cool to make the dancer adjust the intensity of the grove instead of the tempo? I would love to see that, as the dancers movements gets more intense, the beat does the same, causing the dancer to dance even more intense and so on. One of the axis can be used to trig drum rolls of various intensity and so forth.

    I’m impressed!

    • rohdelli!

      Thanks a lot for your feedback.

      That sounds interesting indeed, theoretically that would result in an intensity feedback – dancer vs. machine 🙂

      Basically I intend to play the drums my self, but the concept of intensity is very appealing, I’ll keep it in mind and see what I can do with it!

      Thanks again, I really appreciate comments on my projects.
