Frequently Asked Questions
How do I find out what chord I'm playing?
Open the Chord Finder's Identify from notes mode and pick the notes you're playing, lowest first; on piano you can press the keys in the Piano Chord Lookup instead. Both name the chord, including inversions and slash chords such as C/E.
Should I use the Chord Finder or the guitar and piano chord lookups?
Use the Chord Finder to name a chord or to see its notes on both instruments at once. Use the Piano Chord Lookup for fingerings, voicings and inversions on piano, and the Guitar Chord Lookup for guitar chord diagrams.
How do I find which chords are in a key?
In the Scale Finder, pick the key's scale — such as C major — to see the chords built on each note of it. In the Chord Finder, every chord lists the major and minor keys it belongs to, with its Roman numeral in each.
Which scale should I play over a chord progression?
Start with the scale of the progression's key: C major over a progression in C major, A natural minor over one in A minor. The Scale Finder shows the notes of every scale and mode on piano and guitar, and the chords built from each seven-note scale.
How do I write a chord progression?
Choose a key and mode in the Chord Progression Generator and generate progressions built from that key's chords, then play them to hear how they sound. Common patterns such as I–V–vi–IV are a good starting point.
Why are some notes sharp and others flat?
In the Chord Finder, Piano Chord Lookup, Chord Progression Generator and Scale Finder, each note is spelled from the chord's root or the scale's key, the way sheet music and chord charts write them. E♭ major seventh is E♭ G B♭ D, not D♯ G A♯ D, so every chord tone and scale degree keeps its own letter.
Are these chord and scale tools free?
Yes. Every tool is free to use with no signup.
