If a change of Tempo occurs resulting in three consecutive Musicians playing at three different Tempos, the middle one’s Harmony becomes Dissonant. Any Musician with Dissonant Harmony may often change eir Tempo, unless another musician playing the same instrument also has Dissonant Harmony. A Musician whose Harmony is Consonant may occasionally change the Tempo of any other Musician, unless another musician playing the same instrument also has Consonant Harmony, in which case they may change another musician’s Tempo often. If two musicians with different Harmonies are playing the same instrument, the musician with Dissonant Harmony may often change the Tempo of the other musician, and may occasionally change the Tempo of any other musician.
