The purpose of his task is a test of group entrainment. There are two different groups, and the aim is to maximise entrainment and tempo stability within groups, while minimising entrainment and influence between groups.


Participants are divided into two groups. In each group, a group leader has a metronome. The two metronomes are set to different (non-harmonic) tempi, e.g. 85 and 100 BPM. The game has three stages.

Stage 1:

Stage 2:

Stage 3: 

Each stage could take 1-5 minutes.
