So try to pin down which is in operation in any given discussion. If there's a good reason for the first system, it's yet to reach me. All we need to know is what the tonic is.

The tonic chord of a minor key is i, it contains the minor 3rd above the tonic. The tonic chord of a major key is I, it contains the major 3rd above the tonic. And it's why I recommend the other system, one that aligns with the way we name intervals. What, you might ask, about chords that include the 6th and 7th degrees of the minor scale? Do we name according to the natural, melodic or harmonic form of the minor scale? All three often mix freely in the same piece.

In C major, E major triad is III, in C minor E♭ major triad is III. You can decide what key you're in and name strictly diatonically. There are two systems of naming chords by Roman numerals. Notice the difference in symbols depending on whether you give the key signature before the Roman numeral symbols.

Cm:III is the diatonic chord in C minor E♭ major.

If the music was initially considered to be in C minor, the key signature already includes an E♭ and so no alteration or prefix is involved:

C:♭III is the chord "borrowed" from C minor E♭ major.

Conventionally this is conceived as "borrowing" from the key signature of C minor which has three flats A♭, E♭, B♭, and the diatonic triad in C minor on the third scale degree is E♭ major.

The secondary dominant is sort of the standard harmony analysis way, changing the letter case to alter diatonic from the key signature is more of a jazz way to label chords.) Finally, you could prefix the number with a flat - ♭III - and that would mean the E is altered from the C major key signature to become E♭. To clearly convey that secondary dominant sense, you would write C:V/vi. (A small aside: that chord could be considered a secondary dominant to chord vi A minor. If it were given as C: III the chord would be E major. In case-sensitive style iii is used because the diatonic triad on the third scale degree is minor. in C major, just III could mean simple the third scale degree, E or any triad rooted on E.

a sharp, flat, natural prefixing the Roman numeral means a chromatic alteration from the key signature.

Keep in mind there is a system that simply labels scale degrees with all upper case Roman numerals regardless of chord quality.Īlso, you should give key signatures with Roman numerals for clarity. And there is a sort of matching and alteration that can happen with the symbols depending on the key signature and the intended chord qualities.

Upper case means major triad, lower case means minor (also include suffix o means diminished triad and + means augmented)īut the important thing is the scale in question is given by the key signature.

Roman numeral indicates the scale degree.
