Seven quarters?? Seven four? Seven on four? Harmonic seventh or perfect seventh. Septie`me parfaite. By the way, it's best to write a ratio either like 4:7 or 7/4, but not like 7:4 (unless you mean 4/7). > Does anyone know of a french name for cents??? How do you pronounce it in > french? Aussi cents. Comme "sant"? > What is the minimum number of degrees to have a octave based scale? > What is the minimum number of degrees to have a n-ave based scale? I suppose two, being a pathological case. > What is the maximum number of beats/second the ear can perceive? (is the > number of beats is greater than this number, the interval is not > perceived as "beating" anymore) I do not think that there is a clear border. Beating gradually changes into an increasing roughness of tone. > What is the max freq a human can perceive? (Again, Id like to get the "world > record") >From an old Guinness book of records: "Children with asthma can often detect a sound of 30000 cycles per second. It was announced in February 1964 that experiments in the U.S.S.R. had conclusively proved that oscillations as high as 200000 cycles per second can be heard if the oscillator is pressed against the skull."
