Limited Feedback Interaction networks are divided into two main categories—reciprocal & non-reciprocal—and possess different features (symmetrical vs. asymmetrical). LFI matrices are better suited to certain numbers of players (prime numbers work well), and require a spirit of open-minded collaboration to be successful. They are not limited in size other than by the capabilities of the hardware available; in theory, LFI networks could encompass thousands, if not millions, of people. Types of LFI NetworksReciprocalIn a reciprocal LFI network, each player can hear, and be heard by, the same people. For example, in the following chart we can see each player's headphone-mates:
Since each player can both hear and be heard by the same subset of players, direct musical interaction and imitation can take place. This variety of LFI matrix is the 'drum circle' type, since playing in it is like playing in a drum circle, wherein one can hear one's immediate neighbors, and one's immediate neighbors can do the same. However, each player's "immediate neighors" are unique, which effectively gives each player a unique monitor mix within which to improvise. Non-reciprocalIn a non-reciprocal LFI network, each player cannot be heard by any players whom she can hear. For example, in the following chart we can see each player's headphone-mates:
This type of LFI Matrix usually results in a more chaotic, multi-layered piece of music. Symmetrical vs. AsymmetricalAn LFI matrix's is symmetrical when each participant hears the same number of other players. If LFI matrix participants have differing numbers of 'headphone-mates,' those matrices are asymmetrical. The first example is a seven-person, non-reciprocal symmetrical LFI Matrix:
The next example is a seven-person, reciprocal asymmetric LFI matrix [this particular matrix occurs when one member of the LFI wishes to hear and be heard by all of the others, usually in an effort to conduct their playing].
Potential UsesLimited Feedback Interaction matrices can be used to aid in the creation of any type of improvised music. However, there is also potential for LFI matrices to yield interesting dialogue, productive brainstorming sessions, group-based problem solving, and so forth.
