After thinking deeply about my material I concluded that I needed select the most doable material I had written. On the 19th of September I tried to deconstruct it in fragment.
After have a variation of my motif I started to think about a beginning for my piece. I started with the same motif on the violins and viola, in a hight register, then I did a cannon where the motif is played aleatory and the accents are random.
This gesture goes on until the marimba start playing the same motif in random way too.
For this starting point, the main purpose was to have an in-harmonic sonic result with the odd partials of the harmonic series in D in a aleatoric way. However, it became more ambiguous when the violoncellos start to play, this is caused because violoncellos are playing in a hight register which decrease the possibility of a relieve on a fundamental so what we hear is a kind of harmonic partials all random played in a hight register. To do not lose the principal motif, which is been done by the Marimba, I double it on the violoncello 2.
On rehearsal mark E, bar 68, minute 1'44'' I introduced a new gesture which is other variation of my original one. This will let me go a bit down on the register and prepare the solo part of the Marimba.
On rehearsal mark F, bar 78, minute 2'00'' the gesture returned o the first one, still with fragments of the last. At this time, I did a different cannon. First time I did a cannon, was more and less a bar, at this point is only one bit. This gesture will help me to get down a bit more and continue the preparation for the solo marimba part.
