IV–V–iii–vi in C Major is F – G – Em – Am. Free MIDI download of the progression, with optional 7ths and arpeggios — no sign-up.
IV–V–iii–vi is the J-pop "royal road" progression. Written out in C Major — no sharps or flats — it becomes F – G – Em – Am. The numerals are what stays the same from key to key: IV–V–iii–vi is the same set of relationships whether it lands on F or on any of the other eleven keys, which is why songwriters think in numerals and only pick a key afterwards.
| Bar | Numeral | Chord | Notes |
|---|---|---|---|
| 1 | IV | F | F – A – C |
| 2 | V | G | G – B – D |
| 3 | iii | Em | E – G – B |
| 4 | vi | Am | A – C – E |
Built from the c major scale — C, D, E, F, G, A, B — which is written with no sharps or flats.
Numerals travel: IV–V–iii–vi is the same set of relationships in any key, so if C Major sits wrong for a singer, move it and the shape survives.
Pick a key, a scale, and one of the classic progressions, and this tool writes the chords into a MIDI file you can drop straight onto an instrument track in any DAW. Each roman numeral is voiced as a triad built from the scale — enable 7th chords for a jazzier sound, or arpeggiate to spread each chord into eighth notes. Press play preview to hear the progression before downloading. Here the tool arrives preset to IV–V–iii–vi in C Major, so the file you download voices F – G – Em – Am exactly as shown above.
Because every progression is spelled from the key you choose, moving IV–V–iii–vi out of C Major is one dropdown away — but in C Major itself you get F, G, Em, Am, chords that sit comfortably under most vocal ranges and lead instruments.
Progressions are a starting point — if you want full arrangements with melodies, basslines, and drums written around F – G – Em – Am, open the MIDI Maker studio and generate a complete track.
Or head back to the chord progression tool to build any combination yourself.
