Music Theory QuickThink:

- Identify the key

- The root of the chord is associated with the scale degree number of the key. (Ex. in the key of Bb Major , F is the 5th scale degree)

- Convert the scale degree number to a roman numeral. If the triad of the seventh chord is major , write the roman numeral in upper case: If the triad is minor or diminished, write the roman numeral in lower case. If the seventh chord creates a fully diminished chord add a small circle sign (°) If the seventh chord creates a half diminished add the small circle sign with a slash through it.

- Example: in the key of Bb Major, a g minor triad would be marked as vi

- Expected Roman numerals for chords in a major key (without altering the key signature are…

I7, ii7, iii7, IV7, V7, vi7, vii ø7
