ChordTools is a collection of free online music practice and learning tools. We provide interactive resources for guitarists, pianists, and ukulele players who want to improve their skills, learn new songs, or simply have fun making music.

Whether you're a complete beginner learning your first chord or an experienced player exploring new scales and techniques, ChordTools provides the reference materials and interactive tools to support your musical journey.
Each tool is designed for a specific practice need. Here's what you can do with ChordTools:
A chromatic tuner that uses your device's microphone to detect pitch in real-time. Supports standard tuning (EADGBE) and works for acoustic, electric, and bass guitars. The visual display shows whether you're sharp or flat, making it easy to tune accurately.
An interactive collection of guitar chord diagrams showing finger positions for major, minor, seventh, and suspended chords. Each diagram displays the fret positions and which fingers to use, perfect for learning new chord shapes.
An interactive fretboard that displays scale patterns. Select any root note and scale type (major, minor, pentatonic, blues, modes) to see the notes highlighted across the entire fretboard. Helps you visualize and memorize scale shapes.
Click notes on a virtual fretboard and we'll identify what chord you're playing. Useful when you discover a nice-sounding fingering and want to know its name, or when transcribing songs by ear.
Figure out where to place your capo to play a song in a different key using the same chord shapes. Enter the original key and your preferred shapes, and we'll show you the capo position needed.
An interactive diagram showing all notes on the guitar neck. Use it as a reference while learning or filter to highlight specific notes. Essential for understanding the fretboard layout.
Visual diagrams showing how to play chords on the piano keyboard. See which keys to press for major, minor, seventh, diminished, and augmented chords in all 12 keys. Includes chord formulas and interval information.
Click keys on a virtual piano and we'll identify the chord you're playing. Works with triads, seventh chords, extended chords, and inversions. Great for music theory learning and songwriting.
Tune your ukulele to standard GCEA tuning using your device's microphone. Works with soprano, concert, and tenor ukuleles.
Chord diagrams optimized for 4-string ukulele. Learn the essential chords every ukulele player needs to know.
Visualize scale patterns on a 4-string fretboard. See how scales translate to the ukulele's unique GCEA tuning.

Studying music theory or taking lessons? Our scale visualizers and chord finders help you understand how music works.
Play for fun? Quickly look up a chord you forgot, find the right capo position, or explore new scales when you want to try something different.
Writing your own music? Use our chord finder to identify progressions and our scale tools to find notes that work together.
All ChordTools run entirely in your web browser using modern web technologies. Our tuner uses the Web Audio API to access your microphone and analyze pitch in real-time. Our chord and scale visualizers are built with interactive SVG graphics that work on any screen size.
We don't require any plugins, downloads, or installations. If you have a modern web browser (Chrome, Firefox, Safari, Edge), our tools will work. For the tuner, you'll need to grant microphone permission when prompted.
The site works on desktop computers, laptops, tablets, and smartphones. We've optimized the interface to be usable on smaller screens, so you can reference chord diagrams or tune your instrument using your phone.
ChordTools is completely free to use. We don't have premium tiers, subscription fees, or paywalled features. Every tool on this site is available to everyone, always.
To keep the site running and continue developing new tools, we display advertisements. We try to keep ads unobtrusive so they don't interfere with your practice sessions.
If you find our tools helpful, the best way to support us is to share ChordTools with other musicians who might benefit from these resources.
We're always looking to improve. If you have suggestions, found a bug, or just want to say hello, we'd love to hear from you.
