Hey, the youtube videos are ok, but if you can get a copy of Shawn Stahl's honker talk on DVD you'll be laying it down in no time. The knight and hale call from CT isn't very good to learn with. Once you learn the basics of blowing a short reed the more complicated notes come with practice and familiarity with your call. I owned close to a dozen short reeds before I found the ones I like. Right now I'm using a GK Canuck and a Buck Gardner SS-2.
Here's some quick tips though;
Hand position, place the call in your master hand between your thumb and ring and middle fingers. Your ring finger and pinky stay together and control the pitch of the notes. They control the pitch. Put your non master over your master hand, with your index finger on your non master hand touching the middle finger on your master hand. Thumbs side by side, and your fingers always stay together, keep them cupped.
Mouth position, put your tongue against the back of your bottom teeth, and raise it up to form a narrow air channel in your mouth. Place the mouthpiece of the call on your bottom lip, your tip lip should cut off the top third of your mouthpiece, like your drinking from a bottle.
Presenting air into the call, should start from down in the diaphragm. Don't blow from your cheeks, blow from your belly. Use reference words to make your basic notes. Adding a little inflection (humming/growling) will make your call sound a lot goosier.
Basic Notes;
Moan- long steady note, say "gooooooo" into the call
Cluck- quick note, one of a gooses basics, a quick "hut" into the call, nice and sharp to get the reed to break. The position of your ring a pinky on the master hand will control the pitch. Open your non master hand slightly will make the note sound better.
Honk- starts with a moan, ends with a cluck. Put the moan and cluck together, "gooooohut". Opening your non-master hand at the end of the note.
These are the basics. As you practice more you'll learn the sounds which can be used to make the more advanced notes and the youtube videos will make more sense. Contest calling is a lot different than field calling too, a lot of the stuff you hear on the stage isn't in a gooses vocabulary.
Sorry for the long winded post, I hope this helps.
