What is a high shrill sound ending with wh

A high shrill sound that ends with the letter "wh" could be described as a whistle. It is a high-pitched sound produced by forcing air through a small opening, typically made by pursing the lips or using a whistle instrument. Whistling can be accomplished by shaping the mouth and controlling the airflow. If you want to produce such a sound, you can try the following steps:

1. Position your lips: Pucker your lips slightly, creating a small oval-shaped opening.
2. Control your tongue: Place your tongue slightly below the opening created by your lips to help control the airflow.
3. Blow gently: Blow a steady stream of air through the small opening between your lips.
4. Adjust: Experiment with the positioning of your lips and the intensity of your breath until you achieve the desired high shrill sound.

Remember that whistling can require practice and may vary depending on individual techniques and the context of the sound you aim to produce.
