I–IV–V–IV in B Major is B – E – F#. Free MIDI download of the progression, with optional 7ths and arpeggios — no sign-up.
I–IV–V–IV is the classic rock workhorse. Written out in B Major — 5 sharps (F#, C#, G#, D#, A#) — it becomes B – E – F# – E. The numerals are what stays the same from key to key: I–IV–V–IV is the same set of relationships whether it lands on B 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 | I | B | B – D# – F# |
| 2 | IV | E | E – G# – B |
| 3 | V | F# | F# – A# – C# |
| 4 | IV | E | E – G# – B |
Built from the b major scale — B, C#, D#, E, F#, G#, A# — which is written with 5 sharps (F#, C#, G#, D#, A#).
Numerals travel: I–IV–V–IV is the same set of relationships in any key, so if B 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 I–IV–V–IV in B Major, so the file you download voices B – E – F# exactly as shown above.
Because every progression is spelled from the key you choose, moving I–IV–V–IV out of B Major is one dropdown away — but in B Major itself you get B, E, F#, 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 B – E – F#, open the MIDI Maker studio and generate a complete track.
Or head back to the chord progression tool to build any combination yourself.
In B Major, I–IV–V–IV is B – E – F# – E. Those are built from the b major scale — B, C#, D#, E, F#, G#, A# — stacking thirds on each numeral's degree.
