What is slide whistle?

A slide whistle, also known as a swanee whistle, piston flute, or jazz flute, is a musical instrument that produces sound by air being blown through a mouthpiece that then passes through a resonating chamber with a sliding plunger. By moving the plunger in and out, the player can change the pitch of the sound produced.

Slide whistles are often used in comedy acts, music performances, and sound effects in movies and television shows. They are relatively simple instruments to play, requiring only the ability to blow air and move the plunger to change pitch.

Slide whistles can be made from a variety of materials, including plastic, metal, and wood. They come in different sizes and pitches, from soprano to tenor to bass.

Overall, slide whistles are a fun and playful instrument that adds a unique and whimsical sound to any musical performance.
