[Harp-L] Chromatic vibratto Question

[Mike Rogers <bullfrog9@xxxxxxx>]

When I play my chromatics, I always use diaphram vibratto.  It just 
happens naturally for me and I like the vibratto that I get.  But when 
playing diatonics, I always turn to embouchure vibratto.  My diaphram 
vibratto just isn't as dramatic and takes much more effort, to achieve.  
Just wondering if others experience this and why the chrom. is easier to 
use diaphram vibratto.
I suspect the hole size might be the factor.
