This thesis is concerned with the communication of information using auditory techniques. In particular, a music-based interface has been used to communicate the operation of a number of sorting algorithms to users. This auditory interface has been further enhanced by the creation of an auditory scene including a sound wall, which enables the auditory interface to utilise music parameters in conjunction with 2D/3D spatial distribution to communicate the essential processes in the algorithms. The sound wall has been constructed from a grid of measurements using a human head to create a spatial distribution. The algorithm designer can therefore communicate events using pitch, rhythm and timbre and associate these with particular positions in space. A number of experiments have been carried out to investigate the usefulness of music and the sound wall in communicating information relevant to the algorithms. Further, user understanding of the six algorithms has been tested. In all experiments the effects of previous musical experience has been allowed for. The results show that users can utilise musical parameters in understanding algorithms and that in all cases improvements have been observed using the sound wall. Different user performance was observed with different algorithms and it is concluded that certain types of information lend themselves more readily to communication through auditory interfaces than others. As a result of the experimental analysis, recommendations are given on how to improve the sound wall and user understanding by improved choice of the musical mappings.

We chose a set of them to develop the considerations that we propose on poem, rhythm, sound, music and lyrics, as well as other musical and literary structures. We have seen how the work of this artist is made up: their life histories, the influences that had early in his career, his unique musicality, the correspondences between authors and arts. We weave considerations on literary and musical structures that are interconnected, not to form another art, but to diffuse each as such because each art remains in its compositional artistic envelope. By meshing the interpreter develops between the scholarly and the popular, their songs gain sophistication and uniqueness through their own artistic style. Thus, the relationship of dialogue established between the two arts justify our study, noting the presentation of the invariants of the songs analyzed for its literary and musical nature. / Nesta dissertação, analisamos as características líricas presentes nas músicas de Adriana Calcanhotto, após termos apreciado diversas de suas canções. Escolhemos um conjunto delas para desenvolver as considerações que propomos sobre poema, ritmo, som, letra e música, além de outras estruturas musicais e literárias. Vimos como a obra dessa artista se compõe: sua trajetória biográfica, as influências que teve no início de sua carreira, sua musicalidade singular, as correspondências entre autores e artes. Tecemos considerações sobre as estruturas literárias e musicais que se imbricam, não para formar outra arte, mas para se difundirem cada qual como tal, pois cada arte mantém-se no seu invólucro artístico composicional. Pelo entrosamento que a intérprete desenvolve entre o erudito e o popular, suas canções ganham sofisticação e singularidade por meio de um estilo artístico próprio. Assim, as relações de diálogo estabelecidas entre essas duas artes justificam nosso estudo, observando a apresentação das invariáveis das canções analisadas pela sua natureza literária e musical.
