Hi, Lim I'm sure Bill Bremmer explains it well. The three thirds progress in speed. The lowest is the slowest and highest is the fastest, so to speak. You want the speeds to increase at an even rate. Officially, the ratio is supposedly four to five. That is, for every four beats F-A beats, the A-C# should beat five, and so forth. In actual pianos, the rates don't always have that ratio, but almost always one can make them increase evenly. Hope this helps.
