This educational game is already used in thousands of schools to introduce children to pitch and improve their musical ear for notes. Each of the blobs in the chorus sing a note then king blob sings his note. The aim of the game is to identify the blob that sang the same note as king blob. It’s more difficult than it sounds but if things do get too easy for your child you can increase the size of the choir.

Train your musical ear with this wonderful game! This resource will improve your child’s ability to pick out a note from a sequence.

Great fun app

This is a great fun game and very good for training in your musical ear! Simple to understand, but tricky as you add more blobs. The kids in class love this.
