I hope my multiple “commercial” posts will be tolerated as 50% of the proceeds goes to charity.

Two whistles in one auction? Why? Because they are both cheap and fun. Think of it more like a theme set. Even more fun - 50% of the winning bid goes to charity.
Both whistles are like new, you’ll dig 'em.
One whistle is the Parks Whistles, Ghost Whistle in High D.

- Made from non-petroleum clear tubing.
- Quiet to medium volume.

- Easy to see when the whistle needs cleaning.
- Impervious to soap and water - just wash it out.
- Non-tunable.

The second whistle is a Jubilee Music Instruments & Crafts, Daniel Bingamon made, Plastic Ahava Rabba Whistle.
Also called the “Hava Nagila” whistle. Why Hava Nagila whistle? Listen to the sound clip.
I’ve taught people who have never played a whistle before to play Hava Nagila on this in less than 5 minutes - serious. It’s great fun.
Ok already - time for the sound clips. Just scales: low ocatave (D E F G A B C# D), middle octave (G A B Cnat D E F G), and high octave.
