November 1999: On Muffling: Unit 2: Octaves

Now that we understand the nature of a string's vibration, the next consideration is when to allow it to vibrate freely, when to stop that vibration, and how.

The beautiful resonance of our instrument is, indeed, one of its greatest assets. But there are times when it can become "muddy". For instance, when playing a series of octaves in the lower register the overrring of each one into the next blurs the sound and can also interfere with the harmonic progression of the music. So, in this circumstance we use a technique of damping called "palmed" or "open hand" octaves.

To do this, let's play a scale of octaves starting with A V and A IV. Pluck the A octave with normal hand position. Approach the B octave with your hand open and flat, palm facing the strings. Aim directly for the two B's with your thumb and 4th finger even though the fingers are all pointing upward. Momentarily lay your hand flat on the strings but as you touch the two B's
arch your palm outward so the fingers can grab, curve around, and ultimately pluck them. The 2nd and 3rd fingers move away from the strings as the palm arches outward, and subsequently follow the 4th finger into the hand after plucking.

The intent of this action is to dampen any vibrating strings that fall within the scope of your palm. But remember to aim specifically at the strings you intend to play, not at the ones that are vibrating. Also, you must try to avoid "clawing" your fingers. Admittedly, this is not an easy technique to acquire, but it is well worth the effort once learned.

After you have mastered it, it is also possible to brush lower strings as you approach the new octave, but it is better not to do this until your are comfortable with the first part.

See you next month.
