Numerals that represent a major chord are usually capitalized, and minor and diminished chords are lower case. Roman numerals indicate each chord’s position relative to the scale.

When you add sevenths the chords are Ab major seventh, Bb minor seventh, C minor seventh, Db major seventh, Eb dominant seventh, F minor seventh, G minor seventh flat five. This gives us the chords, Ab major, Bb minor, C minor, Db major, Eb major, F minor, G diminished. The chords in Ab follow the pattern, Major Minor Minor Major Major Minor Diminished. The notes in this scale are Ab Bb C Db Eb F G. But because of notation difficulties caused by the need for a double sharp, this key is hardly used.įirst of all, let’s take a look at the A flat major scale. The key of G sharp major makes use of the same chords and scale notes except that the notes and chords have different names. See pitch (music) for a discussion of historical variations in frequency.What are the main chords in the key of A flat? We will take a look at triads (three note chords) and four note extended chords (with sevenths) in this key. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the G ♭ semitone is approximately 369.994 Hz.

G ♭ is a major third below B ♭, whereas F ♯ is a major third above D (a minor third below A). However, in some temperaments, it is not the same as F ♯. It lies a diatonic semitone above F and a chromatic semitone below G, thus being enharmonic to F ♯ (F-sharp) or fa dièse. G ♭ ( G-flat also called Ges or sol bémol) is the seventh semitone of the solfège.
