L'imaginaire créatif et re-créatif dans les poétiques musicales au deébut du XIX siècle: le compositeur et l'interprète

The creative and re-creative imaginary in musical poetics at the beginning of 19th century: the composer and the perfomer. The musical performance appears as a point of convergence between the creative imaginary and the poetic experience of the composer and between his creative route and the re-creative one of the musical perfomer. The musical work is the result of existential and aesthetic choices and his communication, in the time, must keep intact the creative idea, contained in itself. This is evident in the composer of the early decades of the 19th century, for whom the question of the composer-perfomer was inseparable. This is the case of Chopin and Liszt. The creative and performing poetics were born from individual singularities and philosophical-cultural trends, as it was evident in the French and German musical culture. The choice of Weltanschauungen was reason of the different sensibility, on the plan of the time and memory (the agogics) conception, of the style, of the sound, of the melodic, rhythmic and tonal importance, in an experience between life and art, in which composers, composers-performers are involved. This choise has characterized the performers' history.
