Draw and blow

Hi David, 

I'm a total novice of less than a week with a harp.

I have some experience playing brass instruments in my youth, tenor horn & trombone, both of which rely on blowing only.

I am beginning to get used to the idea of drawing as well as blowing, but I am finding the speed of transition between the two (playing a triplet - blow, draw, draw - for example) quite difficult with any pace.

Transitioning from blow to draw feels very unnatural at the moment. 

Any tips or exercises you can suggest?

Thanks

Adrian
