Tooterühmad
Tooterühmad are small, often handheld, musical instruments that produce sound when air is blown through them or when they are shaken. They are commonly found in toys and novelty items, and are frequently used by children. The sound produced by tooterühmad can vary depending on their design and material, ranging from a simple squeak to a more complex honk or whistle. They are typically made from plastic or rubber. Tooterühmad are not generally considered to be sophisticated musical instruments, but they can serve as an introduction to sound and rhythm for young children. Their simplicity and accessibility make them popular as party favors or small gifts. The term tooterühmad is a colloquial Estonian word that literally translates to "hooter groups" or "tooter groups," suggesting a collection or variety of such devices. While there isn't a strict classification system, tooterühmad encompass a broad category of sound-making toys designed for amusement rather than serious musical performance.
