4) Interactive Lesson: Notate Triads given Roman Numeral

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 g minor, C is the 4th scale degree)

-           Convert the scale degree number to a roman numeral.  If the triad is major or augmented, write the roman number in upper case: If the triad is minor or diminished, write the roman numeral in lower case.  If the triad is augmented add a plus sign (+).  If the triad is diminished add a small circle sign (°)

-           Example: in the key of g minor, a C minor triad would be marked as iv

-           Expected Roman numerals for chords in a minor key

i, ii °, III, iv, V, VI, vii °

-           NOTE: In order to achieve V or vii ° , the 7th scale degree of the minor key must be raised by one half step (an accidental will appear in these chords).  If the 7th scale degree is not raised, the roman numeral quality would be v and VII.  It is more common to see V and vii ° in music, but either is possible.
