Some Technical Vocal Fry Questions

I was watching the lesson on vocal fry from 30day beginner lessons and I realized I had a hard time doing vocal fry. I followed the instructions: relax the jaw and tongue. All I managed to do was a weak breathy tone instead. Before this, I didn't warm up.

I then remembered that to solve breathy tone, do the vocal exercise Guh. I did for a few seconds and I am able to do the fry easily. 

After a while, my tone became breathy again and I have to do the Guh exercise to sort of reactivate the cord compression thingy.

1. Technically, why does good cord compression, in my experience, help with executing vocal fry?

2. How do I practice to maintain good cord compression without having the need to do cord compression exercises frequently during a practice session?

Thanks in advance! :D

1. Vocal fry requires your vocal folds to connect and vibrate together (slowly). If you don't have adequate compression, you'll get mostly air coming through - same concept as when you're singing!

2. I do think that'll come with time; but you can try "resetting" with something like a lip trill, which should also bring your folds together well.

Every exercise has a purpose, and I'm glad to hear you're using the GUH exercise to achieve a specific goal within your practice! That's a good thing!
