Brain Composer: 'Thinking' melodies onto a musical score
Under the title of "Brain Composer", a group led by BCI expert Gernot Müller-Putz from TU Graz's Institute of Neural Engineering shows that experiences of quite a different tone can be sounded from the keys of brain-computer interfaces. Derived from an established BCI method which mainly serves to spell - more accurately - write by means of BCI, the team has developed a new application by which music can be composed and transferred onto a musical score - just through the power of thought. All you need is a special cap which measures brain waves, the adapted BCI, a software for composing music, and of course a bit of musical knowledge.
The basic principle of the BCI method used, which is called P300, can be briefly described: various options, such as letters or notes, pauses, chords, etc. flash by one after the other in a table. If you're trained and can focus on the desired option while it lights up, you cause a minute change in your brain waves. The BCI recognises this change and draws conclusions about the chosen option.
The short video "Sheet Music by Mind" gives an impression of composing music using BCI: https://www.tugraz.at/institute/ine/research/videos/

TU Graz researchers develop new brain-computer interface application which allows music to be composed by the power of thought. How this works is shown in the current issue of the journal PLOS ONE.
