Major foundation
Three functions with strong resolution.
A progression is more useful when you connect function, fingering and voice leading. Learn the harmonic pattern first, then choose guitar voicings that make it playable.
Roman numerals reveal the role of each chord and let you reuse the same progression in new keys.
Three functions with strong resolution.
Four common diatonic functions.
Predominant to dominant to tonic.
A direct minor-key framework.
The closest familiar shape is not always the best musical choice.
Useful in guitar-friendly keys.
Ideal for upper-register movement.
Useful for jazz, blues and richer harmony.
Reduce jumps between roots.
A progression becomes reliable when the weakest pair of chords is reliable.
Repeat only the difficult move.
Keep the rhythm steady before speeding up.
Transpose the same Roman-numeral pattern.
Use these answers as a reference, then explore the relationships interactively.
I–IV–V, I–V–vi–IV, ii–V–I and a basic minor progression give a useful foundation across several styles.
Use both. Chord names help you play the current key, while Roman numerals make the progression portable.
Compare inversions and compact voicings so common tones stay in place and individual voices move by smaller intervals.
Change the key, compare voicings, follow voice leading and see the same idea directly on the fretboard.
