The 7th chord will be built using only the notes of the scale we are interested in. Starting from the 1st scale note, each lesson step below will take each note in turn and construct a 7th chord using that note as the root / starting note of that chord. The piano keyboard below contains the notes of the Gb major scale. This step shows the scale note names that will be used to construct all 7th chords that harmonize with those scale notes. The half-diminished symbol ' ø' is placed after the roman numerals to indicate this is a half-diminished 7th chord.Ĭhord names for G-flat major chord 7 Chord positionį half-diminished 7th chord in root positionį half-diminished 7th chord in 1st inversionį half-diminished 7th chord in 2nd inversionį half-diminished 7th chord in 3rd inversion Just like a minor chord, the half-diminished 7th chord is constructed using a minor third interval, so the roman numeral is shown in lower case. The roman numeral for number 7 is ' vii', and is used to indicate this is the 7th chord in the scale. This subtonic 7th chords root / starting note is the 7th note (or scale degree) of the Gb major scale. The G-flat major chord vii ø 7 is the F half-dim7 chord, and contains the notes F, Ab, Cb, and Eb.        Herearethenamesofthenotesof        thescale,andtheirtriads Ĭhords I to VII in the key of G major.This step shows the subtonic 7th chord of the G-flat major scale.  The subdominant chord (IV) in G major  Fifth  

Primary chords are the tonic (I), the subdominant (IV) and the dominant (V). Sharp and flat meet at the bottom of the circle: F sharp major (six sharps) is the same key as G flat major (six flats) – see page 19. As you move anti-clockwise, they increase by one flat. As you move clockwise by step around the circle, the key signatures increase by one sharp. This chart shows all the major and minor keys and their key signatures.
