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 real playing and instant feedback. The app, now available worldwide, connects music theory with practical piano performance by recognizing chords played on acoustic pianos, electronic keyboards, MIDI devices, or its built-in on-screen keyboard.
Unlike many music-learning apps that focus mainly on theory or memorization, Piano Chord Trainer listens to the notes played and provides immediate visual feedback to help users recognize mistakes, strengthen technique, and build confidence. The app combines flashcard-style exercises, color-coded feedback, and guided practice tools to support skill development across key areas including chord recognition, chord inversions, slash chords, arpeggios, left-hand accompaniment, sight-reading support, ear training, and harmonic understanding.
"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."
One of Piano Chord Trainer's key features is its ability to recognize multiple notes played simultaneously and identify chord structures in real time. This allows users to receive instant feedback while practicing on real instruments, helping bridge the gap between theory and practical performance. By focusing on active practice instead of passive instruction, Piano Chord Trainer helps users develop both musical understanding and physical keyboard skills.
The platform is designed for a wide range of users, from beginners learning basic chord shapes to advanced musicians improving accompaniment and performance fluency. It also supports music educators and institutions looking for structured piano-learning tools, and can be used in 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.
Piano Chord Trainer 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.
