Ear Monkeys is a free music game from Ling's Tales that helps children learn to hear the difference between notes. Each monkey sitting on the branches of the tree sings one note of the scale, from A to G.
The game plays a note, and the player taps the monkey they think sings it. Start on an easier level with only a few monkeys on the tree, then add more as your ears improve. The game runs in the browser on phones, tablets and computers, and can be installed to the home screen.
