Direcionalidade em duas melodias do século XX: Syrinx, de Claude Debussy e a primeira das Três pe？as para clarinete solo, de Igor Stravinsky

the present work analyses the melodic structure of the pieces syrinx, by claude debussy, and the first of the three pieces for solo clarinet, by igor stravinsky, in search of procedures employed to generate the sensation of directionality along the discourse. in order to do so, aspects such as dynamics, rhythmic structure, the organization of the intervals and the movement through the register were taken into consideration. the analysis shows that both composers make use of traditional procedures to make their lines directional, and yet they contribute with new and particular resources.
