Hopscotch has been making catchy educational songs for children for the last 6 years about the solar system, counting, and climate change. Now they've created one for instruments of the (European classical) orchestra.
It's a great resource for younger children, with vibrant imagery and real videos of musicians playing instruments. It even includes melodies from pieces such as Stravinsky's The Rite of Spring and Mozart's Eine Kleine Nachtmusik and others, which could serve as an introduction to some of this orchestral music.
Unrelated to music, I'd also recommend The Boundaries Song, which aims to teach children to speak up if they feel uncomfortable and learn how to set healthy boundaries.
It's wonderful that they've included melodies from well-known pieces, making it a fun and interactive learning experience. Music education at a young age can have a lasting impact, and initiatives like these are invaluable for fostering an early love for music.
