“Lana Tai – no dia em que nasceu uma aquarela”
composing via audio descriptors

This article is a review of a music creative processes in which it was applied compositional strategies combined to sound spectral analysis based on audio descriptors. This procedure supported the creation of the work “Lana Tai – no dia em que nasceu uma aquarela” for string orchestra. For that, some instrumental mixtures and orchestration were made using a Sound DataBase. In this particular case, a virtual environment in Pure Data (PD) software, using the library for analysis fucntions PDescriptors, analyzed some potential orchestral settings. All the results, issues and compositional reflections were used to create “Lana Tai – no dia em que nasceu uma aquarela”. This approach rises up a new contribution in the development of research in both creative processes and the creation of new unpublished works.
