Which D-string should I choose for my violin: aluminum or silver?
The D-string is the leading string of the violin and has the greatest influence on the other strings. When the leading string has too little brilliance, it steals overtones from the adjacent strings. For this reason, the usual choice is a D-string which is 5-10% more brilliant and more metallic sounding than the A- and E-string, as the D-string’s overtones are most quickly reduced.
The aluminum D-string is suitable for instruments that sound very dark or have a poorer bow response. In principle, they sound lighter, a little more metallic, produce more bow noise and have a thicker diameter.
Silver D-strings have a more finely-grained bow noise, a slower response, are thinner and normally sound darker. The sound is broader than with the aluminum D-string and they are suitable for brighter instruments.
