The effect of presence and absence are really interesting to me, and how things can be affected by absence and presence of objects, sounds, people, etc. The idea of live performance mixed with sound installation as a concept emerged for me, dealing with the presence/absence of the ‘virtual’ sounds (electronics) and the ‘real sounds’ (improvised acoustics).
Other related thoughts, which ties into the blend of ‘real’ and ‘virtual’, the presence/absence of either object changes what the art form is contextualized as. When there is no acoustic element, the work is sound art/sound installation. When there is both, it is electroacoustic music/’performance art’(?). Where there is only a musician, it then becomes freely improvised music. If there is a visual element, I believe the improviser (most likely myself) should be blindfolded, so as to not be distracted by the visuals.
Really need to consider the practicality of using VR, lighting systems may be better, and VR may limit the experience to a small group of people. Using Unity with projectors could also work, might possibly be better to work with.
Here is a produced idea, representing ideas of reflection, a mirror harmony, which reflects different musical intervals in a vertical space (Perschetti, 1961, p. 173) This sounds uses a MIDI vibraphone, reversed, with added delay, reverb, and a wee bit of chorus.
Here is what it looks like in staff notation.
