The lowest pitched reeds are the longest in the harp, so they have the largest surface area to catch the most air. Because they catch more air, they take less air pressure to operate. The high reeds, on the other hand, are the shortest, stiffest reeds in the harp. Because they have less surface area to catch air, it takes more playing pressure to get the reed to vibrate at the same amplitude (speed) as a low reed to create a constant tone. Also, I find a little tighter lip purse is required at the top end to make sure all of the air is going into the soundhole you are trying to play. You can get away with less precision on the low end as any air channeled into adjacent holes will just create a chord.

It may help to disassemble an old harp and get a visual reference to this theory for it to make sense.

keep on harpin'...
