For teachers

Free for your whole class

Everything on String Warrior works in any modern browser with nothing to install and nobody to sign up. Share a link and your students are in — on a school Chromebook, a phone at the bus stop, or a practice-room laptop. There's no student data to collect, no cost per seat, and no login wall between a learner and a chord diagram.

Chord and scale references cover 25+ instruments, every diagram has a plain-language description, and the core reference works even with JavaScript off.

Printable handouts & sheets

Hand out something students can write on. Our printables include blank guitar tab, blank fretboard diagrams, chord sheets, staff paper, and wall posters — print them or save as PDF for any instrument.

Every chord page also exports a clean, branded diagram sheet: open a chord in the chord library, pick the voicings you're teaching, and use the handout export to get a printable page of exactly those shapes.

Embed our tools in your site or blog

Teaching from your own class site, blog, or LMS page? Drop in a live String Warrior widget — a single chord, a set of chords, the interactive fretboard, a progression, the metronome, or the microphone tuner. Each is a small iframe that matches your visitors' theme, resizes to fit, and sets no cookies inside your page. Here's a set of first-song chords, embedded exactly the way yours would be:

Grab the copy-paste snippet for any widget — and a live preview of each — on the embed page. Every widget carries a small link back here, so it's a friendly way to credit the source too. Prefer a plain image for a worksheet, Markdown handout, or LMS page? Every chord is also a self-contained SVG you can drop in with a bare <img> — no iframe or script.

Accessible for every student

The tools are built to work for the whole room. The tuner can speak each detected note aloud and announces sharp/flat through a live region, so a student can tune without watching the screen. The metronome has a silent visual-only mode and haptic vibrate alongside its click, so the beat is something you can see or feel, not only hear.

Every colour theme is contrast-checked in our build and chosen to stay distinguishable for colour-blind players, diagrams mirror for left-handed students with one toggle, and the whole site honours reduced-motion and zoom. More detail is on our accessibility page.

Structured practice & theory

Send students home with a plan, not just a worksheet. Learn lays out step-by-step paths from first chords onward, Practice offers guided routines per instrument with a built-in player and streaks, and Theory covers the circle of fifths, modes, CAGED, intervals, and progressions with interactive diagrams you can pull up mid-lesson.
