Open D tuning is an alternate guitar tuning where the strings are tuned to D-A-D-F♯-A-D (from lowest to highest). This creates a D major chord when you strum all six open strings, making it perfect for slide guitar, fingerstyle playing, and creating rich, resonant chord voicings. Open D tuning is especially popular in blues, folk, and rock music.

Use our chord finder tool to discover any chord in open tuning. Simply select your root note (like C, D, or G), choose the chord type (major, minor, 7th, etc.), and select which strings you want to play. The tool shows you every possible voicing on the fretboard with proper interval labels, making it easy to learn new chord shapes.

Yes! Our tool supports multiple open tunings including Open D, Open E, Open C, and Open B. Each tuning creates different chord possibilities and tonal colors. Open E is great for slide guitar, Open C provides deep bass tones, and Open B offers even deeper bass tones. Simply select your desired tuning from the dropdown menu.

You can play all chord types in Open D tuning, including major, minor, 7th, 9th, sus2, sus4, diminished, augmented, and jazz extensions. Our tool includes 32 different chord types across all 12 chromatic root notes (plus 5 enharmonic notes), giving you access to over 500 chord voicings. Popular chords include D major, A major, G major, D7, and Am.

Open D tuning works with all scales and modes. Our tool includes 67 scales including major, natural minor, harmonic minor, melodic minor, pentatonic scales, blues scales, and exotic modes like Dorian, Phrygian, Lydian, and Mixolydian. The tool shows you every scale position on the fretboard with interval labels (root, 2nd, 3rd, etc.).

In standard tuning, guitar strings are tuned E-A-D-G-B-E. In Open D tuning, you tune down the 1st, 2nd, and 6th strings to create D-A-D-F♯-A-D. This open tuning produces a D major chord when strummed open, enables easier barre chords, creates unique voicings, and is ideal for slide guitar. Many famous songs use Open D including "The Cave" by Mumford & Sons.

A chord voicing is a specific way to play a chord on the guitar fretboard. The same chord (like D major) can be played in many different positions and string combinations, each creating a unique sound. Our chord finder shows you all possible voicings for any chord, sorted by pitch from lowest to highest, so you can choose the voicing that sounds best for your music.

The Circle of Fifths is a music theory tool that shows the relationship between different keys and scales. In our chord finder, the Circle of Fifths displays which scales and keys contain your selected chord, color-coded by scale family (major, minor, harmonic, melodic, pentatonic). This helps you understand which scales to use for soloing and improvisation over specific chords.

Our interactive fretboard shows a visual representation of the guitar neck. Horizontal lines are strings (top = 1st string/high D, bottom = 6th string/low D in Open D tuning), and vertical lines are frets numbered 0-22. Colored circles indicate where to play notes, labeled with both the note name (D, F#, A) and interval degree (R for root, 3 for third, 5 for fifth, etc.). String numbers appear on the left, and "0" at the nut indicates open strings.

Modes are scales derived from the major scale, each starting on a different degree. The seven main modes are Ionian (major), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (natural minor), and Locrian. Each mode has a unique sound and emotional character. Our tool shows 162 modes across different parent scales, complete with chord progressions and fretboard positions for each mode.

A harmonized scale is when you build chords on each degree of a scale. Our tool displays these as interactive chord progression tables on the Scales and Modes tabs. For example, harmonizing the D major scale creates chords: D major (I), E minor (ii), F# minor (iii), G major (IV), A major (V), B minor (vi), and C# diminished (vii°). Click any chord in the table to see it on the fretboard, or use the "Play" button to hear the progression—perfect for understanding how chords function within a key.
