The web art project Neorganologium (https://neorganologium.blogspot.com/) presents a collection of infra-instruments and circumstantial instruments. Infra-instruments, according to Bower and Archer (2005), are instruments with "restricted interactive potential", which leaves "little opportunity for conventional virtuosity". Among the types of infra-instruments discussed in the article, the project has objects that are not originally instruments and objects that originally had the status of toy instruments and the like. Circumstantial instruments are instruments that are inseparably part of the environment. Portability of circumstantial instruments is an impossibility or is very difficult and their use occurs in situ.
