The 8 essential beginner shapes

How the chord trainer works

1. Pick your chords

Choose a preset group — open chords, barre chords, power chords, or the famous progressions of the keys of G, C, and D — then toggle individual chords on or off. Start with two easy shapes like Em and Am, and add more as your changes get faster.

2. Strum before the bar runs out

A target chord and its diagram appear with a countdown. Form the chord and strum — the chord recognition engine listens through your microphone and scores the change the moment it hears the right notes. Play the wrong chord and it knows, even when the bass note matches.

3. Beat your best

Each hit shrinks the timer, so the trainer keeps pace with you — just like practicing with a teacher who pushes a little harder every round. Three misses ends the run; then check your score, best streak, and fastest change, and go again.

Why chord change speed matters

Slow chord transitions are the #1 thing that makes beginner guitar playing sound choppy. Songs don't wait — a G to C change has to land on the beat, every time. Drilling changes against a timer builds the muscle memory that turns individual shapes into smooth playing.

AI Chord Practice gives you the feedback loop that silent practice can't: it confirms every change was actually clean. Muting a string or landing on the wrong third doesn't count, so you build accurate habits instead of fast mistakes.

Before you start, make sure you're in tune with thefree online guitar tuner, and look up any unfamiliar shapes in thechord library— 150+ diagrams across all 12 keys.

AI Chord Practice FAQ

How does AI Chord Practice hear my chords?

It listens through your microphone and analyses the audio in real time, matching the notes you strum against the target chord. Everything runs locally in your browser — no audio is recorded or uploaded.

Is the chord practice trainer really free?

Yes. AI Chord Practice is completely free, with no sign-up, no app download, and no time limits. Open the page, allow the microphone, and start practicing.

Which chords can I practice?

Six preset groups: open chords (C, D, E, G, A, Em, Am, Dm), barre chords (F, B, Bm, F#m, Gm, Cm), two power chord sets covering low and movable positions, and the famous chord progressions of the keys of G, C, and D. You can toggle individual chords in every group.

Does it work for acoustic and electric guitar?

Yes. Any guitar your microphone can hear works — acoustic, electric through an amp, or classical. A quiet room and clean strumming give the most accurate detection.

How do I get faster at chord changes?

Practice a little every day. Start with two chords, keep your fretting fingers close to the strings, and let the shrinking timer push your speed. One-minute bursts between songs add up quickly.
