The Avatar Orchestra Metaverse consists of members based in Europe, North America and Asia.^{[2][better source needed][3]} The core membership ranges between 8 and 12 members who are artists from music, sound art, visual art, new media, architecture and other disciplines. This, however, is not a fixed number, with the orchestra's additional members changing on a semi-regular basis. The group was founded by composers Hars Hefferman and Shintaro Miyazaki aka Maximillian Nakamura, who were active in the group until 2008. Current active members include transdisciplinary artists Björn Eriksson (Sweden), Tina M. Pearson (Canada), Norman Lowrey (USA), Leif Inge (Norway), Frieda Korda (Belgium), Max D. Well (Germany), Viv Corringham (UK/USA), Johannes Riedmann (Germany), Chris Wittkowsky (Germany), Brenda Hutchinson (USA), Gema FB Martín (Spain), and Harald Muenz (Germany). Former members who have created and collaborated on works for the Orchestra include Pauline Oliveros (USA), Jeremy Owen Turner (Canada), Andreas Mueller (Germany), Biagio Franca (Italy), Tim Risher (USA) Sachiko Hiyashi (Sweden), Liz Solo (Canada), and Stelarc (Australia) among others.^{[4][better source needed] [5][better source needed]}

This membership makes use of Second Life to perform telematically with each other, using virtual instruments which commonly created specifically for the composition they are used in.^[6] One example of these instruments is the 'Onomatophone', six spheres which move around the virtual space emitting separate sounds to the audience, the purpose of which being to change the sounds heard by different audience members depending on their own proximity with the separate spheres.^{[7][better source needed]}

In certain cases, the membership's avatars themselves are modified and used as the instruments within the performances. To do this, AOM members make use of a HUD, containing various sample sounds, which – when played – also highlight the avatar in some manner, to make the audience aware of which participant is 'playing' at that point.^{[8][better source needed][9][better source needed]}

Due to the virtual nature of the group, they have been able to perform live around the world via streaming to various countries. Countries they've performed in include France, Germany, Norway, Sweden, Italy, Spain, the Netherlands, Canada and the United States. This had also allowed them to perform for various performative festivals, including Sound Symposium XVI.^[10]
