This 2-player game is perfect for beginners learning unisons, 2nds and 3rds on the musical staff.
Grab a friend and race to see whose character climbs to the top of the rope faster. Each interval you get correct moves you up the rope, while wrong answers make you slide down.
Customize the settings:
- Play with your choice of intervals, unison through thirds. Perfect for students learning skips & steps.
- Play with harmonic or melodic intervals.
- Include/exclude ledger lines
- English or Italian ordinal number abbreviations.

Change the theme to see the characters throw different objects. New seasonal themes become available every 3-5 weeks, in addition to ongoing themes of sports, music and chess.

Tap the clef mark to change between treble and bass. Tap the eye icon to show/hide the clef mark.

What teachers are saying:
"Healthy competition is a stimulus for concentration... I let [a student] start alone and then begin the frantic chase. I like that this application makes it possible to identify the interval using a number. A child must first be able to differentiate a third from a fourth or an octave and only then whether it is perfect, major, minor... It is also interesting that the interface of this application is minimalist, eliminating unnecessary distractions." - Ricardo M.
