Counterpoint is when two or more voices are in a relationship with each other, but not necessarily a platonic one. Considering the case of two voices, they may be different in contour and rhythm (termed straight voices), or they may be more or less the same (termed gay voices). When more than two voices join in the same bar(in music, bars are a scientific way to measure if a composer is alcoholic(many bars per composition) or not(less bars per composition)), I forgot what I was talking about. Oh yeah, when more than two voices join in the same bar then the relationships are not clear. Maybe they are cheating on each other.
