“…This outlines the need for more generalized devices and analysis algorithms available for the artistic community at large and its proper documentation. Due to the complex nature of the field there is the need for a bridge that conveys the knowledge gathered by the dedicated researchers working on BCMIs and the wider interactive arts community (for recent work on this area see Grierson & Kiefer (2014) and Miranda & Castet (2014).…”

Whalley, Mavros and Furniss explore questions of agency, control and interaction, as well as the embodied nature of musical performance in relation to the use of human-computer interaction through the work Clasp Together (beta) for small ensemble and live electronics. The underlying concept of the piece focuses on direct mapping of a human neural network (embodied by a performer within the ensemble) to an artificial neural network running on a computer. With our commentary, we contextualize the work within the field of Music Neuroscience. Specifically, we point at precedents in EEG-based musical practice as well as ongoing research in the field. We hope to more clearly situate Clasp Together (beta) in the broad area of Brain Computer Musical Interfaces and discuss the challenges and opportunities that these technologies offer for composers.

Composing only by thought: Novel application of the P300 brain-computer interface

The P300 event-related potential is a well-known pattern in the electroencephalogram (EEG). This kind of brain signal is used for many different brain-computer interface (BCI) applications, e.g., spellers, environmental controllers, web browsers, or for painting. In recent times, BCI systems are mature enough to leave the laboratories to be used by the end-users, namely severely disabled people. Therefore, new challenges arise and the systems should be implemented and evaluated according to user-centered design (USD) guidelines. We developed and implemented a new system that utilizes the P300 pattern to compose music. Our Brain Composing system consists of three parts: the EEG acquisition device, the P300-based BCI, and the music composing software. Seventeen musical participants and one professional composer performed a copy-spelling, a copy-composing, and a free-composing task with the system. According to the USD guidelines, we investigated the efficiency, the effectiveness and subjective criteria in terms of satisfaction, enjoyment, frustration, and attractiveness. The musical participants group achieved high average accuracies: 88.24% (copy-spelling), 88.58% (copy-composing), and 76.51% (free-composing). The professional composer achieved also high accuracies: 100% (copy-spelling), 93.62% (copy-composing), and 98.20% (free-composing). General results regarding the subjective criteria evaluation were that the participants enjoyed the usage of the Brain Composing system and were highly satisfied with the system. Showing very positive results with healthy people in this study, this was the first step towards a music composing system for severely disabled people.
