 # ECC-RAM
 
 Electronic Chamber Choir - Random Access Music
+
+## Basic Idea
+
+The ECC is a swarm of independent small devices (called "singers") which perform
+a piece of music together.
+
+### Initial state
+
+When the ECC starts (or as been freshly reset) every singer randomly chooses a
+voice out of the "score" (probably a voice out of a MIDI-file) at a random
+position and starts singing.
+
+### Synchronisation
+
+Every singer has, apart from his main audio autput (loudspeaker or piezo), also
+an supersonic sender/receiver facility over which he sends what he is currently
+singing and tries to listen to other singers trying to broadcast their position.
+Over this supersonic interface now the singers try to synchronise themselves
+while still singing, preferably starting with adjusting to direct neighbours
+forming local clusters and then the clusters trying to synchronise each other.
+
+Once synchronisation is complete, the piece of music performed will be audible
+in all its aspects.
+
+### Resetting
+
+Every singer has a photosensitive element on them, which can react to sudden
+changes in lighting conditions (e.g. when exposed to a camera flash). When
+triggerd, avery singer affected resets and begins at a new initial state.
+
+apart from this there can also be other ways of resetting single choir members
+or the whole choir.
