source file: mills2.txt Subject: Barbershop From: John Starrett Ladies and Gentlemen- I have had a request to supply more info on barbershop music. The full correct name of the organization is "The Society for the Preservation and Encouragement of Barbershop Quartet Singing in America " and the compilations of each years winning quartets is available on the ProArte label. I own two of these, "Coney Island Baby" from 1990 and "Old Mill Stream" from 1991. Some of these groups sing "justly" and without much vibrato.

It's so simple it should be translatable into other dialects of Basic without difficulty. 10 Print "Input the numerator and denominator of the ratio" 20 Print "and this program will give the cent value" 30 Print 40 Print "numerator": Input A 50 Print "denominator": Input B 60 Let R = A/B 70 Let C = 1200 * LOG(R)/LOG(2) 80 Print "cent value of ratio" A"/"B "is" C What it does is divide the logarithm of the ratio by the logarithm of 2(because it's an octave) then multiplies by 1200 for the number of cents to the octave. If you want to use Yamaha tuning units instead of cents just replace the 1200 by 1024. Brian Lee
