On Mapping EEG Information
into Music
Joel Eaton and Eduardo Reck Miranda
Abstract
With the rise of ever-more affordable EEG equipment available to musicians,
artists and researchers, designing and building a brain
computer music interface
(BCMI) system has recently become a realistic achievement. This chapter
discusses previous
-
research in the
fields of mapping,
soni
cation and
musi
cation in the context of designing a BCMI system and will be of
particular interest to those who seek to develop their own. Design of a BCMI
requires unique considerations due to the characteristics of the EEG as a human
interface device (HID). This chapter analyses traditional strategies for mapping
control from brainwaves alongside previous research in biofeedback musical
systems. Advances in music technology have helped provide more complex
approaches with regard to how music can be affected and controlled by
brainwaves. This, paralleled with developments in our understanding of
brainwave activity has helped push brain
computer music interfacing into
innovative realms of real-time musical performance, composition and applica-
tions for music therapy.
