A classic toy, the slide whistle is a great introduction to music! By simply blowing on the whistle and using the sliding internal bar, children will create sounds that are high, low and everywhere in between. A great exploration of notes and melody creation that can sound super silly or really beautiful - it's up to you! The whistle measures 7.5" long and is crafted from chemical free rubber wood with a non-toxic, clear-coat finish over German-made, VOC free water-based paint. At Green Tones we believe that every child is born with an innate musicality and through nurturing music will grow in your child. Studies show that music is not only fun but beneficial for critical cognitive development. Imagine a thick forest with no clear pathways through it - this is like the developing brain of a child. Now visualize the pathway being forged, neurologically, every time you musically interact with your child. The "music channel" is similar to the "language channel" in the sense that it needs to be stimulated every day in order for it to grow and be strong. As one of the oldest professional musical instrument companies, we believe that every day is a good day for music play. At Green Tones we are passionate about providing a musical foundation with a focus on incorporating the highest quality woods that are sustainably produced, beautiful to see and feel and safe for your child. From sustainable products to sustainable packaging to giving 1% of our profits to groups caring for the environment, we are committed to doing the right thing for you, your child and the planet.
