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.

Good concept, sub-par execution


This is a great concept for a game/learning tool, and could be very useful if a few things were changed. I agree with another reviewer who said the easier settings should use wider intervals that are easier to hear (4ths, 5ths, tritones, etc). Additionally, the vocal samples used make it very difficult to tell what pitch they're actually singing. There's a very wide, uncentered vibrato on many of them, which totally skews the pitch center, making it sound only about 40 cents away from a note that is probably meant to be a half-step away. If you used samples in a different tessitura and with a clearer pitch center, this app would be 10X better, and I would pay money for it.

Thank you for the constructive feedback. You've provided some very specific ideas for improvement there. Very much appreciated. Thank you.

SBE Loves Blobs


I use this app in my music class and the students love it. I do have some exceptional students and they have a difficult time hearing some of the lower pitches. This game would be perfect if the tones were clearer and soprano and alto voices were included as an option. Also, some of the tones are 1/4 steps apart (a little out of tune) making the app difficult to match the pitch since it falls in between the cracks. Otherwise, this is a great app and has much merit.

Wish it used a wider range of notes


It seems like this would be obvious, but here goes: The easier levels should involve comparing VERY different pitches to make it....easier.

For example, the king blob sings C4. The other blogs sing C4, Bb4, and F3. It's much easier for a new learner to pick the right pitch because the other options are so obviously far away from C4. Move the note options closer in pitch to the correct note as the game progresses to make it more difficult.

Also in general, this game should utilize more range. Untrained ears (children especially) have a hard time discerning notes that are out of their singing range.

This game is a great idea, could use a little more tweaking to make it actually effective.
