About
Hear an interval, a triad or a 7th chord, name it, and find out instantly if you were right.
A daily streak and a 30-day accuracy chart show whether your ears are getting sharper.
Fully on-device: no cloud, no account.
Each drill is a handful of questions: play the sound, pick the answer. Intervals from unison to octave, triads, 7th chords and scale degrees. When you want more than the daily drills, the Lessons tab holds a full course.
• Intervals, triads, 7th chords and scale degrees
• Feedback after every answer
• A daily streak
• A 30-day accuracy chart
• Ear Course: 172 lessons in 20 chapters, from octaves and thirds to extended chords, modes and melodic dictation
• Sound Engineer: name frequencies, EQ bands, reverb times and compression ratios
• Review: what you keep missing comes back on a spaced schedule, with your weakest facts, custom lessons and theory cards
• Progress for every lesson of the course
For students with a theory or aural exam coming, singers, players who want to work out songs by ear, and engineers training their ears for EQ.
Everyone gets the first chapter of the course, plus five a day shared by the drills, the other chapters and Sound Engineer. Pro, or SUS4 All-Access across the whole range, removes the daily limit.
Made in the UK by working musicians.
