Chordex 和弦圖鑑

Here's a natural, App Store–ready English version:

Chordex is a chord-learning companion built for guitar beginners and self-taught players. It's more than a chord lookup tool: it helps you understand the music theory behind every chord, so you go from just being able to play it to actually knowing how to use it.

Chord Changes Pick the chord transitions that trip you up, practice along with the beat, and turn chord switching into muscle memory.

Chord of the Day Get a new chord every day based on the date, complete with a short intro and key theory notes. Over time, you'll build your own personal chord dictionary.

Full Chord Library Around 46 essential voicings, organized by type: major, minor, seventh, suspended, and more. Search by name or attribute (like "Cmaj7" or "sus"), and jump straight to everyday chords like C, G, Am, Em, and D with a single tap.

In-Depth Chord Details Each chord comes with a fingering diagram and a full fretboard view. Tap to hear a realistic strum. You'll see the chord's notes, its interval structure, and the role it plays in a key, along with the classic progressions it shows up in and suggestions for similar chords. Save your favorites and come back to review anytime.

Key Explorer Browse all 12 major keys arranged on the Circle of Fifths. View each key's scale and solfège, its diatonic triads and seventh chords, and its chords grouped by tonic, dominant, and subdominant function, plus the classic progressions that work in that key. Whether you're writing, figuring out a song by ear, or transposing, you'll know where you're headed.

Reverse Chord Lookup Press your fingering onto the interactive fretboard, and Chordex instantly identifies the chords it could be. Preview the sound and tap through to the full details. Spotted an unfamiliar shape in a chord chart? Play it in and find out.

Strumming Practice Five practical strumming patterns built in: quarter-note downstrokes, folk starter, all-purpose folk, full eighth-note strum, and slow pop ballad. Each pattern loops alongside a rhythm diagram, with adjustable BPM and the option to switch practice chords. Ghost-strum explanations help you build a steady, reliable right hand.

Classic Chord Progressions Nine timeless progressions, including the Canon progression, the pop four-chord loop, Doo-Wop, the jazz ii–V–I, and the blues. Loop them and strum along chord by chord until your ear knows the backbone of popular music.

Theory Articles Illustrated music-theory guides with chord diagrams, triad comparisons, and capo charts. Each article links directly to the chords and keys it covers, so you can read and practice at the same time.
