Learn and practice intervals and ear exercises with YY the squirrel! YY Teaches Intervals is a suite of deceptively simple but extremely effective music games that can be played alone or with teachers, parents, and friends. Built by lifelong musicians and teachers, and starring nationally recognized violinist Ben Chan and his furry friend YY the squirrel, this app trains students on difficult ear and interval concepts so that teachers can focus their lessons on musicality and performance. Interval Acorns gradually introduces intervals across nine levels, 5 instruments, and several modes (including chords). Any student who graduates through Level 9 is guaranteed to be able to recognize intervals up to an octave in almost any real world situation! Likewise, Scale Sprouters gently introduces students to 13 scales and modes (including Blues, Mixolydian, and Pentatonic) as they are tasked with sorting the notes from lowest to highest. Even completing the lowest levels reinforces major and natural minor scales in students' ears.

I don’t really think the acorn intervals does a whole lot, as the acorns are always labeled (so kids see text labels rather than hear intervals to distinguish correct answers). The scale flower pots seems ok, but I think some other games might get similar ideas across better. ## Frequently asked questions about YY Teaches Intervals ### What is YY Teaches Intervals?
