Chord progression generator and practice guide

A chord progression is a sequence of harmonies. Use the tool to explore movement between chords, then turn a short sequence into a repeatable exercise on your instrument.

Start with I–IV–V in C major

In C major, I–IV–V means C–F–G. Play each chord for one bar in 4/4. Count all four beats even while preparing the next shape. The exercise is to arrive with the next bar, not merely to find the next chord.

Hear a different journey

Try I–vi–IV–V: C–Am–F–G. The lowercase vi is a minor chord. Listen to the change from C to Am before adding a complicated rhythm. Then compare the sequence with I–V–vi–IV: C–G–Am–F.

Make the difficult change smaller

When F to G is the sticking point, alternate only those two chords at a manageable tempo. Return to the full progression once the change is repeatable. Practise the exact voicings you intend to use.

Transpose with understanding

Roman numerals describe a chord’s role in a key, rather than one fixed chord name. I–IV–V becomes G–C–D in G major. The circle of fifths and chord explorer are useful next stops when the names and relationships are still unfamiliar.
