Independent developer Martin Galchutt has announced the global expansion of Piano Chord Trainer, an iOS application designed to help piano students, teachers, and self-learners improve chord fluency through active playing and instant feedback. Unlike many music-learning apps that focus on theory or memorization, Piano Chord Trainer enables users to practice chords on an acoustic piano, electronic keyboard, MIDI device, or the app's built-in on-screen keyboard. The app listens, analyzes the notes played, and provides immediate visual feedback to help users recognize mistakes, strengthen technique, and build confidence.
"Many aspiring musicians learn melody but struggle when it comes to harmony, accompaniment, and chord fluency," said Martin Galchutt, creator of Piano Chord Trainer. "I created Piano Chord Trainer to help musicians connect what they see in lead sheet music with what they hear and physically play on the keyboard." The app combines flashcard-style exercises, color-coded feedback, and guided practice tools to support skill development in chord recognition, inversions, slash chords, arpeggios, left-hand accompaniment, sight-reading, ear training, and harmonic understanding. It is designed for a wide range of users, from beginners learning basic chord shapes to advanced musicians improving accompaniment and performance fluency.
A key feature of Piano Chord Trainer is its real-time chord recognition capability, which identifies multiple notes played simultaneously and analyzes chord structures instantly. This allows users to receive immediate feedback while practicing on real instruments, bridging the gap between theory and practical performance. By focusing on active practice instead of passive instruction, the app helps users develop both musical understanding and physical keyboard skills. The platform also supports music educators and institutions, offering guided exercises and scalable learning support for private lessons, classrooms, and independent practice sessions.
With support for more than 30 languages, Piano Chord Trainer is reaching learners across multiple countries and continues to expand its global user base. The app is available now on the Apple App Store for iPhone and iPad. Users can begin with a free trial and choose subscription levels based on their skill level and learning goals.
