Starting known-key comparison
| Quantity | Value |
|---|---|
| Starting and comparison keys | A minor → C major |
| Relationship | Relative keys |
| Shared pitch classes | A · B · C · D · E · F · G |
| Shortest tonic shift | +3 semitones; the modes still differ |
| Supported key set | 12 major and 12 natural-minor keys |
| Manual plan limit | 12 key entries |
Compare two keys you already know
Choose a starting key and a comparison key using standard major and minor names. The result shows their relationship, the scale notes they share and the shortest signed semitone movement between their tonics. The initial A minor and C major pair is a relative-key relationship.
The comparison uses major and natural-minor scales. Shared notes describe a useful harmonic connection, not the probability that two recordings will blend. Their basslines, actual notes, tuning, rhythm and phrasing still determine what you hear during a transition.
Explore the fifths circle without memorizing codes
Choose the same key, relative key, neighboring fifths or parallel key from the relationship list. The optional circle offers another way to choose keys in the current mode. Both views operate on the same comparison, so the diagram is not a separate task to complete.
Hear the two key chords auditions simple tonic triads in sequence. These synthesized references help compare tonal centers; they are not the sounds of your tracks. A tonic shift also leaves a major-versus-minor difference unresolved, so transposition alone does not make every pair equivalent.
Keep a practical manual key-order plan
Add comparison keys to an ordered plan of up to 12 entries. Remove entries or undo changes, then copy or download the text plan. A settings link restores the selected keys and manual order without starting sound.
Use the plan alongside your own listening and DJ or production software. This page works from keys you supply: it does not detect recorded keys, retune files or connect to a track library. It uses standard musical key names rather than proprietary wheel codes.
Common questions
Does the wheel detect the key of a song?
No. Supply keys you already know. The wheel and comparison describe relationships among 12 major and 12 minor keys; they do not analyze an audio file.
Do shared notes guarantee a smooth harmonic mix?
No. They identify scale overlap. The tracks’ actual notes, basslines, tuning and phrasing matter, so listen to the intended transition rather than treating overlap as a compatibility score.
Can I save a sequence of keys for a set?
Yes. Build a manual order of up to 12 keys, copy or download its text plan, or copy a settings link. No account or connected music library is required.
