Whistling does count!??People call it annoying, but only if you don't use it like an instrument.??Dynamics, techniques, and all that.
Most people just blow with a constant amount of force.??Try blowing less for lighter passages, louder for more fervent motifs, and adding some
vibrato!
Oh yeah! Learn to whistle while
inhaling so you never have that intrusive gasp! Hooray for unique music experiences!
