-**The string quartet**\\ 
-\\ 
-As mentioned in the abstract, this piece was composed as a proof of concept that could allow posterior assessment of the artistic potential of such an approach to composition.\\ 
-In this sense, the global structure was kept relatively primitive in order to clearly demonstrate the capabilities of the algorithmic structure alone.\\ 
-That being said, the algorithm was used to composed the 'fixed media' part (tape) but not the instrumental part.\\ 
-Nonetheless, since the tape was kept intact after being computed, the instrumental part had to be written accordingly.\\ 
-Consequently, the taped material (its phrasing and its pitch content) was further analysed cognitively and computationally in order to inform the instrumental part.\\ 
-\\ 
-Schematically speaking, the algorithm was then used on three levels of the composition: the movements, the sections and the segments.\\ 
-The movements of the piece come from a raw clustering ran upon the initial sound file database (about 300 different sound files ranging from 30sec to 0.5sec).\\ 
-As the algorithm ended up finding six relatively clear subgroups, or timbre categories, the piece was divided into six distinct movements.\\ 
-Since the machine-learning is unsupervised, meaning the classes are unknown, I'll let you the leisure of finding your own words to describe the six categories...\\ 
-Then, the sections and the sub-sections are simply the result of a second run of the same algorithm on each of the previous six subgroups separately.\\ 
-As described earlier, the resulting structure is a two-layer minimum spanning tree (MST) for which,\\  
-in this case, the global structure (inter-cluster) represents the sections and the local structures (intra-clusters) represents the segments.\\  
-From another perspective (bottom-up), the sound files are locally sequenced to create segments then,\\  
-these segments are themselves sequenced to create sections and finally,\\ 
-the sections are also sequenced to create the movements.\\

-**Audio recording (reading session)**\\ 
-\\ 
-Version using the augmented instruments, meaning that the tape is played directly through the body of the four string instruments.\\ 
-The premiere as well as a studio recording are planned at the end of January 2018 with the TANA string quartet: https://www.quatuortana.net/ \\
