A violia, XXi ths woman in lha nationally advertissd
television commerical, doesn't get older, it gets better.
At least that's whit University of Wisconsin-Madison
Physics Prof. William F, Fry seemed to say Thursday
afternoon in his lecture "The Staph Fhysies of the Violin-Did
Stradivari Have a Secret?" The lecture at the
Wcstbrook Music Eldg. wts sponsored by the UNL Physics
Dept. and the School cf Music.
Fry, who has used his physics skills since 1964 to
understand sound concepts in making violins, said an
older violin exposed to sounds for a period of time will ,
have a better sound than a "gRn" violin. From this,
he sdd, ha has ltsrntd to prematurely se violins to inv
prove their sound quality.
'If you put 50 watts cf acoustical energy in a violin,
in 10 minutes you ran tell the difference. It plays better,"
he siid. Varnishing a violin also changes its acoustical
properties, he ssid. Varnish "freezes in" some cf the
sounds the violin has heard , giving it better tone.

Calling the violin a "complicated instrument," Fry
explained other physics-related problems in ranking vio
lins. Because the violin is a small instrument which emits
higher frequency sound waves, it must be designed exactly
for highest quality sound, he sdd.
The back and the front of the violin must be arched
both horizontally and vertically to stiffen the wood,
Fry said. However because the vertical and horizontal
measurements of the violin differ, the arching creates an
imbalance which must be corrected. This Is done by
varying the thickness of the violin's wood. Using electron
ics, a balance point Is found, he si! J, and the violin emits
a better sound. -
In his lecturo, Fry also spoke about the history of the
violin and the csrly violin maker, Stradivari. Fry sdd he
believed Stradivari's success was due to his understanding
of soma of the physical problems involved in manufactur
ing violins. For 70 years of his life, Stradivari made mors
than 35CO but probably less the SjDOO violins, Fry said.

Daily Nebraska photographer Kevin
Ksley is a finalist in the 1977 William
Randolph Hearst Photojournalism contest.
The annual competition is sponsored by
members cf the American Association of
Schools ml Departments of Journalism.
Haley's entries included a photo story on
last year's Republican National Conven
tion. I Us portfolio included a sports photo
of Husker defensive end Ron Pruitt pinch-
ing a University cf Kansas ball carrier.
The picture was published last fall in First
Down, the Daily Nebraskan football pro
gram. A photo of last year's Pathfinder Hotel
explosion and fire in Fremont also was
entered,
Higley will reprint his portolio, which
wEl be entered again in competition with
the 19 other finalists.
