Understanding Chord Types
Our database spans everything from simple triads to rich jazz voicings — here's what each family brings to your sound.
Major Chords
Bright, happy sound. Root + major 3rd + perfect 5th — the foundation of most songs.
Minor Chords
Darker, melancholic tone. Root + minor 3rd + perfect 5th — essential for emotion.
Seventh Chords
Dominant, major and minor 7ths add tension and color — the heart of blues, jazz, and funk.
Suspended Chords
Sus2 and sus4 swap the 3rd for a 2nd or 4th, giving an open, unresolved sound that begs to move.
Extended & Added-Tone
6ths, add9, and 9th/11th/13th chords stack notes beyond the octave for lush, sophisticated voicings.
Diminished & Augmented
An altered 5th creates instability — diminished feels tense, augmented feels dreamy. Great as passing chords.
Power Chords
Root + 5th only (with optional octave). Strong, neutral sound perfect for rock and metal.
Learning Tips
Start with basic open chords and practice smooth transitions between them. Use a metronome to develop timing, and experiment with different voicings on the fretboard. Learning your favorite songs is the best way to apply chords musically and build muscle memory.

Frequently Asked Questions
Instruments, chord types, alternate voicings and alternate tunings.
- Is the Acousterr chord finder free?
- Yes — every chord, diagram and fingering is free to look up, with no account and nothing to install.
- What is a chord finder?
- It is a tool that shows you exactly where to put your fingers to play any named chord on your instrument. You pick the root and the quality — C, Am, Gmaj7 — and it draws the shape, names the notes in it, and plays it back.
- Do I need to know music theory to use it?
- No. Pick a chord and an instrument and the finger positions appear — nothing else is required. The notes and intervals are shown alongside if you want to know why the shape is what it is, but you can ignore them entirely and just play.
- Which instruments and chord types are covered?
- Guitar (6-, 7- and 8-string), bass (4- and 5-string), ukulele, mandolin and piano, across 22 chord qualities on all 12 roots. That covers major and minor, power chords, sixths, sevenths (dominant, major, minor and half-diminished), sus2 and sus4, add9, the extensions through 9th, 11th and 13th, and diminished, diminished 7th and augmented.
- Can I hear a chord as well as see it?
- Yes — press Play and the chord is strummed back using a sampled voice of the instrument you have selected, so you can check a shape by ear before your fingers know it.
- How are the finger positions shown?
- Two ways at once. A hand visualisation highlights each finger in place on the fretboard or keyboard, and beside it a standard chord diagram numbers the fingers and marks open strings with O and muted ones with X.
- Does it show more than one way to play a chord?
- Yes. Most chords have several common voicings, and you can step through them with the arrows — from the open shape down at the nut to barre shapes further up the neck. Each one gets its own diagram and its own fingering.
- Can I look up chords in an alternate tuning?
- Yes — pick a tuning in the finder and the shapes are recalculated for it. Note that a chord page URL such as /chord-finder/guitar/Cmajor always means the chord in STANDARD tuning: an alternate tuning is a choice you make in the tool, deliberately not baked into the address, so a link you share can never quietly answer a different question than the one it names.
- What is on an individual chord page?
- The chord's notes and the intervals that build it, every common fingering as a diagram and as a fret string such as x32010, and a plain-text diagram. The pages are server-rendered, so they read correctly with JavaScript off and can be quoted by an assistant.
