EGK CTransposer

EGK CTransposer is a powerful chord transposition and composition tool designed for musicians, composers, and songwriters. Whether you're writing a new song, adjusting for vocal range, or learning chord progressions, this app simplifies the entire process.

Easily input a single-line chord progression or paste full lyrics with embedded chords using Chord Sheet Mode. The app intelligently detects chords using regex and instantly transposes them by any number of semitones, with support for sharps, flats, and minor chords.

Visualize the first chord with built-in fretboard diagrams, and hear how it sounds with real-time audio playback using tone synthesis. Save and manage your favorite chord progressions, or export the transposed result as a .TXT file for sharing, printing, or rehearsal use.

Whether you're practicing, performing, or composing, EGK CTransposer brings convenience and inspiration to your musical workflow — powered by EGK Innovation.
