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.

You mentioned contiguous 3rds-F-A, A-C#, C#-F. I can understand the beat rates for these 3rds, but what is the 'evenness' like for these 3rds? Are they supposed to be smooth or what kind of feel is it? How do I know if it is good? Thanks!
