RESUMO

This work focuses on computational environments which use the Logo programming language, directed towards the musical context As an available resource for the individual to access the musical field, there is a need to broaden some characteristics of this language, airning at creating a learning environment which offers more opportunities for the musical "making"of the Learner. Some experiences with Logo-music served as a starting point (pan I) for the search of understanding, at a theoretical level, of topics such as music education, computing and musical creation. In the second pan of this dissertation we look for a theoretical basis for questionings originated from experiences with Logo-music. We consider at this time the importance of the music for the individual and the way education has treated his/her acting in the musical context From this point on, we do consider the need to rethink education in such a way that it considers the individual s needs and interests, as well as the technological advance. We also consider some ideas that support the Logo computational learning environment The third pan raises questions concerning the composing process the problem of the composing process was investigated through interviews and experiments with composers (toy-problem). From the collected data an ana1ysis is carried out trying, at first, to describe the dynamics of acomposer s cognitive work during the design of bis or her composition aiming at the specification of parameters for the development of a musical environment, based on the computer. The data obtained from tire toy-prob1em experiment are ana1yzed according to the microgenetic approach, so that we can describe. the dynamics of the composer s cognitive action during the composing activity. The dynamics of the action is described in its intentional and causal aspects. pointing out the top-down and bottm-up movements respectively. FínaIly, in the fourth part, we indicate some parameters for the design of a computational environment of musical experimentation. The data obtained from the experiments which were carried out indicate that several mechanisms can be added to the Logo computational system. such mechanisms would work as supporting tools for the individual s accomplishments of ideas in the musical field
