What are Roman numerals in chords?
In traditional music theory, Roman numerals (I, II, III, IV, and so on) represent both the degrees of the major scale and the chord quality of each chord. Uppercase Roman numerals represent major chords, while lowercase numerals represent minor chords.
How do you write inverted Roman numeral chords?
The Roman numeral system can also indicate inversions. First inversion is represented by a small 6 after the numeral. This is due to the root being a generic sixth above the bass note. Second inversion is represented with both a small 6 and 4.
How do you label augmented chords with Roman numerals?
Uppercase Roman numerals with a “ ” are augmented (e.g., “ III ”), and lowercase Roman numerals with a “ ” are diminished (e.g., “ vii ”). (There is also the Nashville Number System, which uses Arabic numbers for chords instead of Roman numerals.)
What is the symbol for Roman numerals?
The Symbols
The Roman numeral system uses only seven symbols: I, V, X, L, C, D, and M. I represents the number 1, V represents 5, X is 10, L is 50, C is 100, D is 500, and M is 1,000. Different arrangements of these seven symbols represent different numbers.
