Chord & Mode Explorer
Build the song first. Greywake separates pitch-collection fit, tonal-center evidence, and modal identity, explains non-diatonic harmony, changes note priorities by style, and turns the result into something you can practice on guitar.
Choose the chords from the song
No chord-name typing. Start with the actual progression before choosing a scale.

Likely tonal centers and modes
Greywake separates which seven-note collection fits, which chord sounds like home, and whether a specific modal identity is actually established. One chord is never enough to identify a mode confidently.
How the analysis works
The engine evaluates chord-tone compatibility, tonic placement, repetition and cadential motion, characteristic modal tones/chords, common secondary dominants, harmonic-minor V chords, and common borrowed harmony. The result is a teaching hypothesis, not an absolute label; what sounds like home remains the decisive evidence.
Same harmony. Different priorities.
The genre choice changes the note hierarchy, target-tone emphasis, and practice guidance. It does not pretend that a different genre always requires a different scale.

What each chord is doing
Diatonic, borrowed, secondary-dominant, harmonic-minor, and chromatic roles are separated so an altered chord does not automatically invalidate the home key.
Five musical directions
Suggestions are tied to the selected tonal center and describe the intent before you add the chord.
