Chordly
Tune the guitar. Then keep going.
Chordly is a guitar bench that lives in the browser. The flagship is a standard-tuning tuner. Around it sit the jobs that usually mean another tab: drop D, a metronome, chord shapes, string tension, and a page you can print for tonight’s practice.
Tools in this section
Online guitar tuner
Tune all six strings to concert pitch in the browser. Targets are E2 82.41, A2 110, D3 146.83, G3 196, B3 246.94 and E4 329.63 Hz.
Alternate tunings
Four tunings players actually ask for, each with its own target pitches. Not four copies of the standard tuner.
Guitar testing
Separate the jobs: a pitch readout, a fret-by-fret intonation log, and a spectrum view. None of them claims to diagnose a broken guitar.
Guitar audio tools
Three different jobs: a steady tone to match, a click that keeps time, and a view of the spectrum or waveform. None of them is the tuner.
Guitar calculators
Two quiet tools: where each fret sits for a scale length, and how hard a string pulls at a pitch. Neither one listens to the microphone.
Chord tools
Look up a grip and its notes, move a progression into another key, or download a page of diagrams. None of these pages listens to the guitar.
Learning
A fretboard trainer for note names, a scale chart you can print, and the metronome when the notes need a tempo. Not another copy of the tuner.
PDF generators
Build a chord chart, a scale sheet or a one-page practice plan in the browser. The file is created on your device. Nothing is stored on a server.
Maintenance tracker
Wipe, windings, fretboard, hardware, jack, tuners, case, a 12th-fret comparison and a note about buzz. Log a string change. Download a PDF. Nothing is saved in the browser.
The signal never leaves the page
Start tuning and the browser asks for the microphone. A YIN pitch detector estimates the fundamental, names the nearest note, and shows cents against equal temperament. Nothing is uploaded, and there is no account to create. Close the tab and the audio is gone.
One bench, different jobs
The tuner pages are not copies of each other. Drop D only moves the low string. Open G is a major chord at the nut. The chromatic tuner ignores string targets. Calculators, the fretboard trainer and the PDF sheets each answer a question the tuner does not.
Questions
- Does this work on a phone?
- Yes. Chrome, Edge, Firefox and Safari on a current phone or laptop can run it. Tuning needs a microphone and a secure page.
- Will it diagnose a buzzing fret or a bad neck?
- No. It reports pitch. Setup problems can change the reading, but the page cannot inspect the guitar.
