Ionisation

Definition

Ionisation refers to the process of converting an atom or molecule into an ion by adding or removing charged particles, typically electrons. In the context of sound and music, ionisation can relate to how electronic instruments and innovative sound technologies have changed the way music is created and perceived, allowing for new sonic possibilities beyond traditional acoustics.
