PART TWO: SPRINGS

A ‘spring’ is a procedure or device at the piano, by which energy is gradually stored up, over a relatively long period of time, and then released in its entirety very suddenly.  A electrical capacitor has the same function.   In filling a container with water using the kitchen faucet, for a while no water is flowing over the brim, then suddenly it begins to do so.

Another Example:

Another example is the watch-spring in a pre-digital, mechanical watch.  The spring needs to be wound up.  It then expands, due to its elasticity.  It yields its energy in sudden and small spurts over a relatively long period of time because it is governed by an “escapement”.  If however the escapement suddenly breaks, the spring unwinds completely and suddenly, yielding in that instant the same amount of energy as it would have yielded during all the hours that the watch would have been ticking before the spring needed to be wound up again.

The example of the mechanical watch provides another model of how the pianist can use a spring, this time not in one sudden release, but a series of partial, but sudden, releases, with some short amount of time (maybe one note’s worth) in between one release of energy and the next.  It releases a “tick” at a time.

There will be future posts detailing individual springs in the body.

🙂 Comments, questions, disagreements, all welcome.
