Rhythm Ears is a free violin rhythm game and metronome game built for aural training. Rather than testing pitch, it isolates rhythm on its own — from simple crotchets and quaver pairs up to semiquaver groupings and minims — so students can train their music ears to recognise rhythmic patterns quickly and confidently. It's a natural next step after open-string and note-reading games, and pairs well with steady metronome practice at the instrument.
