## What is ChordTrainer?

ChordTrainer is a focused practice tool for pianists and music students who want to recognize chords by ear and by sight.

Practice triads and seventh chords across all keys, hear them played back on a clean piano keyboard, and test yourself with quick ear-training drills. Each session adapts to what you are working on, so you can drill just major and minor triads, or push into dominant, diminished and half-diminished sevenths.

FEATURES
• Chord recognition drills for triads and seventh chords
• Ear training: hear a chord and identify its quality and root
• Interactive piano keyboard with clear note labels
• Inversions practice — root position, first and second inversion
• Instant feedback so you learn from every answer
• Progress tracking to see which chord types need more work
• Clean, distraction-free interface designed for short daily practice
• Works fully offline — no account required

WHO IT'S FOR
Beginners learning their first chords, intermediate players building fluency in all twelve keys, and music theory students preparing for aural exams.

No ads. No sign-up. No data collection. Just practice.
