By Paul Stein: Chords are some of the most joyous notes to play, and they certainly add depth and majesty. However, three and four - part chords are often accompanied by enormous weight that can upset the balance of the bow. Transferring from the bottom two strings to the top two can double the amount of pressure on the strings. There are technical and aeronautical thoughts you can use, though, to keep all movements as frictionless as possible. Playing with the right bow speed and bow distribution will greatly improve your chords.
Changing Speeds in an Instant
It takes a plan and a lot of chutzpah to start a four-note chord. First count to yourself, then start the chord with great speed and no hesitation. Getting from the bottom to the top of the chord involves so much action, its best to not think while youre doing it. That said, the thinking occurs before and after, just not during.
Before the chord: take a moment to visualize what is happening: The bow is balanced over the lower two strings. The movement that follows is 100 percent horizontal so the bow can skim the lower strings. That initial moment of thrust is followed immediately by a switch in angles. This is an example of Fritz Kreislers popular saying that technique is a matter of pulling the trigger and shooting. Once you "pull the trigger," theres no time to think.
Making Very Abrupt Changes of Angles
One need look no further than a steep rollercoaster to imagine a quadruple-stop. Being fully seated in the track is pretty much how it feels to be in the string. There is one big difference - the acceleration and deceleration are reversed. The chord starts suddenly, with an enormous amount of momentum. By contrast, rollercoaster reaches the apex of the angle steadily and slowly. Then comes the massive free-falling part, with the coaster gripping the track at breakneck speed. Violinists do the opposite and hold back the speed right after crossing to the other side of the angle. This is a good way to learn how to save bow. The beginning of the chord and the transfer to the upper strings takes place in the lowest eight inches of bow. Its like landing on a tiny runway, with a panoply of speeds, saved bows, and angles.
The Weightless Midway Point of the Chord
The half-way part of a chord rests on the middle string, which will be the one with the highest altitude. For a triple-stop on the lowest strings, it would be the D string. For a quadruple stop it would be both the D and A. Two things need to happen to avoid crushing this string (or strings): restrain the weight of gravity, and barely move the bow while its transitioning to the top of the chord. The tendency is to crush the middle string because its not only closest to the hair, and its vibrating into the string. To compensate for the close proximity between the hair and a string moving up-and-down, you need to pull the bow away from the string, while gravity is lowering it. On the violin, gravity always needs to be managed and minimized. You can get deeply into the string, where all the intensity and color are located, with balanced, skimming pressure. I think of this as neutral gravity.
The Muscle Memory of Chords
Adjusting the flight of the bow and moving quickly will result in more balanced sounds. To eliminate scratching, finish the entire movement of the chord as soon as you start it. You may have to break the old habit of using too much bow weight, but the better result will help prevent it from recurring.
