Why StrumAndKey
Most chord sites bury the actual chord shape under ad units, autoplay video, and a wall of song-tab links you didn't ask for. StrumAndKey does one thing: it shows you the chord, the scale, or the theory concept you searched for, clearly, with a crisp SVG diagram (never a blurry scanned image) and real interval math underneath it — see /methodology/ for exactly how every chord and scale is computed.
StrumAndKey covers chord shapes, scales, and music theory — all facts, freely explainable. It never publishes tabs, chord-sheets, or lyrics for any specific copyrighted song. That's a deliberate line, not an oversight: chord shapes, scales, and theory are facts about music that anyone can explain; a specific song's tab, chord-sheet, or lyrics belong to that song's writer. StrumAndKey stays entirely on the facts side of that line.
The site is organized instrument-first, because a C major chord is genuinely a different physical shape on guitar, piano, and ukulele — different strings, different keys, different tuning conventions — not the same diagram relabeled three times. Scales and theory topics sit alongside the chord library so the "why" behind a shape is always one click away, and the 6 practice tools (tuner, metronome, transposer, and more) run entirely in your browser.
FAQ
- Does StrumAndKey have tabs or chord sheets for specific songs?
- No, and it never will. StrumAndKey covers chord shapes, scales, and music theory — all facts, freely explainable. It never publishes tabs, chord-sheets, or lyrics for any specific copyrighted song. Song-specific tabs and lyrics are copyrighted; chord shapes, scales, and theory are facts, which is what this whole site covers.
- Is this really free, or is there a catch?
- Every chord diagram, scale page, theory topic, and all 6 practice tools are free, with no login and no usage cap. There's one optional paid Chord Reference Pack (printable PDFs) for people who want an offline/printable version.
- How are the chord diagrams generated?
- Every chord's real notes and intervals are computed from its root note and quality using standard music-theory interval formulas — see /methodology/ for the exact method and how fingerings are sourced.
- Which instruments does StrumAndKey cover?
- Guitar, piano, and ukulele, each with its own chord roster sized to that instrument's real common chord vocabulary — not just a guitar chart relabeled.
- What are the 6 free tools?
- Chord Finder, Chord Progression Transposer, Instrument Tuner, Metronome, Scale Visualizer, and Chord Progression Builder — all client-side, nothing you play or type is sent to a server.
