Three is a special number. The existence of something is one. The existence of this something automatically generates that which is other than it, so one and two arise together. Three is the field constituted by these two different things, the spectrum between them and the meeting point. The number three appears in many religions and philosophical systems as symbolising equilibrium and perfection. It can definitely be understood like that, if we think that it represents the integration of duality. In any situation in which we are torn in two… finding the third voice inside us might be the well-rounded solution (or well-triangled solution?!).
In a duet, the two performers have equal importance. This balance does not imply that they both do the same thing, or that they do different things for an equal amount of time each. Duality pervades the way we perceive reality and often we see one of the poles as positive and the other as negative. However, in a duet no such vision is possible, because both performers are working at the service of the composition. Sometimes it can be difficult to accept that someone has a different way of going about things. It might be useful to approach whatever we are doing together as a duet, letting differences exist and finding the synergy between them.
