Frequently Asked Questions — Chord Chart Generator

What is a chord chart?

A chord chart shows the chords of a song in order — usually written above the lyrics — so you can play along on guitar, piano or keyboard. This free chord chart generator builds one from plain ChordPro text and draws a fingering diagram for every chord you use, plus optional Nashville numbers and automatic key detection.

How do I find a guitar or piano chord?

Open the Chord Finder, choose guitar or piano, pick a root note and a chord type (major, minor, 7, m7, maj7, sus4 and more). A fingering diagram appears instantly — press Play to hear it.

How do I read a guitar chord diagram?

The six vertical lines are the strings (low E on the left to high E on the right) and the horizontal lines are the frets. A dot shows where to press a string, a number tells you which finger, an O above a string means play it open, and an X means don't play that string.

Can I transpose a chord or a whole song?

Yes. In the Chord Finder the transpose buttons shift a single chord by semitones. In the Song Chart builder they shift every chord in the song at once, and the diagrams update automatically.

How do I write a song chart?

Use ChordPro format: put chords in square brackets right before the lyric, like [G]Happy [D]birthday to [Em]you. Lines starting with # become section headers. The chart shows chords above the words plus a diagram for each chord used.

Can I share or print a chart?

Yes. Copy share link encodes the whole chart — title, lyrics, chords, instrument and key — into the URL, so anyone who opens it sees the same chart. Print gives a clean, ink-friendly page. Nothing is stored on a server.

Can I play a chord progression on a loop?

Yes — open the Progression Player, type a sequence like C G Am F, set the tempo (BPM) and beats per chord, then press Play loop. It cycles hands-free with an optional metronome while the current chord lights up and its diagram shows below. Perfect for drilling chord changes.

Can it tell me what chord some notes make?

Yes. Reverse Lookup gives you a clickable guitar fretboard or piano keyboard — select the notes you're holding and it names the matching chord(s). Click a result to load it straight into the Chord Finder.

Does it detect the key and show Nashville numbers?

Yes. In the Song Chart the tool detects the most likely key from your chords. Switch the Display between chord names, Nashville numbers and Roman numerals, and override the key the numbers count against if you disagree.

What is ChordPro format?

ChordPro is a simple plain-text way to write song charts: type the lyrics and put each chord in square brackets right before the syllable it lands on, like [G]Happy [D]birthday. Lines starting with # become section headers. It's the only thing to learn, and the tool turns it into a neat chart with diagrams.

What is the Nashville number system?

The Nashville number system writes chords as scale degrees (1–7) instead of letter names, so the same progression works in any key — for example 1 5 6m 4 is C–G–Am–F in the key of C. In the Song Chart you can switch the display between chord names, Nashville numbers and Roman numerals.

Which instruments does it support?

Guitar (standard tuning) and piano/keyboard. Every chord gets a real fingering diagram for the instrument you pick — a fretboard shape for guitar or a highlighted keyboard for piano — and you can hear it played back through your browser.

Does it work on my phone? Do I need to install anything?

It works in any modern mobile or desktop browser with nothing to install and no account to create. The layout is responsive, so the chord finder, diagrams and song charts all work on a phone or tablet as well as a laptop.

Does it track my practice or playing?

No. There is no account, no analytics on what you play, and no practice tracking. Everything runs in your browser and nothing is uploaded.

Is this tool free?

Yes, completely free — no limits, no watermark, no ads. It is one of the free browser-based tools at jasperbernaers.com.

A free chord chart generator for guitar and piano

This chord chart generator is a fast, free, browser-based tool for looking up chords and building song charts. Use the chord finder to get an instant guitar chord diagram or piano chord for any root and quality — major, minor, 7th, maj7, m7, 6, sus2, sus4, diminished, augmented, add9 and extended 9th chords — and press play to hear it strummed or blocked through the Web Audio engine. Every chord shows real fingering, so it doubles as a guitar chord chart and a piano chord chart in one place.

Build, transpose and share song charts

Paste lyrics with chords in ChordPro format and the song chart maker lays the chords neatly above the words and draws a diagram for every chord in the song. Transpose a single chord or the whole song up or down by semitones with one click, detect the key automatically, and switch the display to Nashville numbers or Roman numerals. Loop any chord progression hands-free with a built-in metronome to practise changes, or use reverse chord lookup to name a chord from notes you click on a fretboard or keyboard. Copy a share link to send a chart to a bandmate, or print a clean, ink-friendly copy.

Everything runs 100% client-side: no sign-up, no upload, no ads and no practice tracking. It's one of 146+ free browser tools at jasperbernaers.com — pair it with the guitar tuner, metronome and virtual piano.
