the 1st, 3rd, 5th and 7th positions relative to that 2nd root note. The second 7th chord below will repeat this, but this time starting on the 2nd note, so its notes will be Ab, Cb, Ebb and Gb - ie. Identifying the 4 notes in the chordħth chords are built using the 1st, 3rd, 5th, and 7th notes of a scale, so the first 7th chord below will constructed a chord using notes Gb, Bbb, Db and Fb. 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 natural minor 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 minor chord 2 Chord positionĪb half-diminished 7th chord in root positionĪb half-diminished 7th chord in 1st inversionĪb half-diminished 7th chord in 2nd inversionĪb 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 2 is ' ii', and is used to indicate this is the 2nd chord in the scale. This supertonic 7th chords root / starting note is the 2nd note (or scale degree) of the Gb natural minor scale. The G-flat minor chord ii ø 7 is the Ab half-dim7 chord, and contains the notes Ab, Cb, Ebb, and Gb. This step shows the supertonic 7th chord of the G-flat minor scale.
