Learn to recognize chord progressions by ear with real recorded music. ChordProg Ear Trainer has exercises for chord, interval and scale practice, from identifying individual sounds to following a whole progression. Listen to a clip and name the chords in order. Replay a passage when you need another listen, and switch between chord names and Roman numerals to practice recognizing each chord's role in the key. More than 500 recorded clips give you practice across different keys and voicings. Focus on the sounds you want to recognize. Practice telling chord types apart, hearing the distance between two notes or identifying a scale as it plays. Work through short levels and return to the ones you find difficult. Your results and daily streak help you keep track of your practice. When you want to understand what you heard, look it up in the chord, interval and scale dictionaries. You can also tap notes on the piano to find matching chords and scales. Try introductory levels without a subscription.
