Etude 2

This etude is mainly about 2 things. The first is to explore micromusic. And the second is about rhythm.

What I in this case mean by micromusic is sounds that are very short. Maybe 20 milliseconds or so. The thing that happens is that the parameters that determine the character of the sound are different then for longer sounds. It becomes more gestures with qualities such as wood, metal and “noisy”.

The rhythm that I have been working with here is a variant of Olivier Messiaen’s additive rhythms. That kind of rhythms is also found in indian classical music. It is different from our traditional rhythm which is built with hierarchical relations. There your have whole notes that is divided into 1/2, 1/3, 1/4 and so on. Additive rhythm is built around horizontal relations. In the example below 2/16 is related to 3/16.

My variation is that I build the rythm in two layers. The first layer defines the atoms or grains  that you can build rythms of.

You then define the abstract rythm that you want to work with. If we take the first example we will get the following rythm.

2 2 3 2 3 3 2 3

When you apply the abstract rythm on top of the atoms you get the following result.

In the following short example the atoms is built by repeating extracted time-atoms from the harmonic series.
