About this app

This is an all-in-one guitar learning app for those who want to properly learn guitar chords.

Chorditor provides a guitar chord editor, chord chart saving, chord progression practice, scale training, chord memorization quizzes, and playing technique training all in one app.

───────────────────

Guitar Chord Editor

────────────────────

It is a guitar chord editor that allows you to accurately configure 12 key modulations, sharp/flat conversions, and triads, sevenths, tensions, and fractional chords (slash chords). Create your own guitar chord charts and save them as PNG images to use immediately for lesson materials, guitar sheet music, and YouTube tutorial video thumbnails.

────────────────────

Chord Progression & Playback

────────────────────

You can save, play, and practice frequently used guitar chord progressions. Try creating your own chord progressions for various genres, including pop, ballads, jazz, and bossanova. Rhythmic practice is possible with BPM settings and metronome functions.

Guitar Chord Memorization Quiz

────────────────────

This is the most effective way to memorize guitar chord names. You can memorize them step-by-step, from basic triads to jazz tension chords, through level-based multiple-choice quizzes. It also provides reaction speed measurement, a timer mode, and result statistics.

Scale Training (Improvisation)

────────────────────
Master guitar scale blocks and improve your improvisation skills. Visually learn scale patterns by position, and practice switching between paired blocks to freely utilize the entire guitar fretboard.

This is a stroke training system that allows you to repeatedly practice guitar stroke patterns. Practice step-by-step, from basic down-up strokes to complex rhythm patterns!
