A simple HowTo for whistling with two hands, or "birdcalling" as some people call it. This trick takes practice and takes a while of getting used to. Many people fail and give up but the true "Brotherhood" does not.
(The Brotherhood was the origin of this, they started it and passed it down to many, you can trace your Brother line on the last step)
Step 1: Layout
This step is simple (In fact mostly all of them are, but you get it). Lay your hands out flat, like in the pic. This step helps the overall performance, your palm should be inlet to a bowl-like shape. Keep your fingers and thumb straight.
Step 2: Curving
This step may seem very easy but it may change the whole tone and even the volume. Curve your right hand to a slightly angled curve, as if a hand to cover your mouth while yawning (I actually yawned just now while writing XD ) Now make your left hand into one as you would shake someone elses hand but curve the tip slightly, about 20-30 degrees. Now collapse the two hands together and press your thumbs together.
Step 3: Blowing
The goal of this step is to create the tune, or sound. Blow into the curved oval formation until you get a gentle rolling which creates a whistling tune.
To create an actual bird call lift the "flap" created by the overhang of four fingers over the left hand (depends) this creates a rolling tone.
