Counterpoint Gives Two Voices the Right to Disagree

A singer approaches what sounds like the last note of a phrase. A second voice keeps speaking across it. The second may have started the most important part of its sentence on the beat the first voice needed as a place to come to rest. Both accounts can be clear. The combination lets a listener hear an ending that has had to happen inside the continuing life of somebody else. One melody harmonised prettily would have difficulty describing that situation alone.

This is my favourite reason to care about counterpoint. It permits a relationship which the person paying attention to only one line could get wrong with complete musical competence. The lower part may be wandering toward what seems a decisive resolution. The upper line could sound as though it has already got there and is growing impatient. The agreement between notes at a given moment is a small piece of evidence compared with the intentions one imputes to the lines as they take their time.

Letting the other voice finish

Rhythm makes a similar possibility available with very plain pitched material. Divide twelve small pulses into groups of three in one part and groups of four in another. Each can feel settled to the person doing it. Their attacks keep placing weight on events the other part considers unexceptional until there is a shared point of return. Used carefully, the combined pattern can make it seem as if the piece is answering two different accounts of the length of a thought. You can hear the disagreement without learning its arithmetic.

The danger of treating this as a source of sophistication is that every voice starts demanding to be noticed all the time. A listener may hear a large number of real events with little sense of which differences matter. Counterpoint does quite subtle work when one part can accompany another and then continue into a place the apparent lead was prepared to leave behind. The degree of independence can change. There is a great deal to be learnt from the moments when one voice is willing to become ordinary long enough for another to be heard.

Sometimes the most persuasive resolution is a pair of sounds that keep a little of their former disagreement. They arrive somewhere together without adopting the same manner of arrival. There is something believable about a relationship that can give both the shared point and the distance they travelled a musical existence. A single person could have written all of it. The work can still contain evidence of more than one life.
