Chord Finder
Identify chords from the notes you play. Enter 2-3 notes to find matching chord names and structures.
How to Use This Calculator
- Play a chord on your instrument and identify the notes you\'re playing.
- Enter 2-3 of those notes into the calculator (select from the dropdown menus).
- The calculator searches for chords that contain exactly those notes.
- Review the matching chords to identify what chord you\'re playing.
Chord Finding Algorithm
The calculator uses pattern matching to identify chords:
2. Compares against known chord patterns (Major, Minor, 7th, etc.)
3. Finds chords where all your notes match the chord structure
4. Returns matching chord names with their full note sets
Example: Entering C, E, G matches C Major (C-E-G) and could be part of other chords. Adding more notes narrows down the results.
Full Description
Sometimes you hear a chord or play one on your instrument but don\'t know what it\'s called. The Chord Finder helps you identify chords by matching the notes you play to known chord structures. This is especially useful for learning songs by ear, transcribing music, or understanding the harmony in pieces you\'re studying.
The calculator works by comparing your input notes against a database of chord patterns. It looks for chords that contain exactly the notes you enter, considering all possible chord types (major, minor, 7th, etc.). If multiple chords match, it shows all of them so you can determine which one fits your musical context.
Use this tool when learning new songs, analyzing harmony, or trying to understand chord progressions. Enter the notes you hear or play, and the calculator helps you identify the chord name and structure. This is a valuable tool for ear training and music theory learning.
Frequently Asked Questions
How does chord finding work?
The calculator compares the notes you enter against known chord patterns. It matches your notes to chord structures (major, minor, 7th, etc.) and identifies which chords contain exactly those notes.
Why do I need to enter 2-3 notes?
Most chords contain 3 or more notes. Entering 2 notes gives many possible matches, while 3 notes narrows it down to specific chords. The calculator finds chords that contain exactly the notes you enter.
What if I get multiple results?
Multiple results mean your notes could be part of different chords. For example, C-E-G could be C Major or part of A minor 7th (A-C-E-G). Try adding a 4th note to narrow it down, or consider the musical context.
Can I find chords with more than 3 notes?
Yes! The calculator supports 7th chords and other extended chords. Enter all the notes you're playing, and it will match them to the appropriate chord type, including complex chords with 4 or more notes.
