@Alfred It is clear you do not know what augmented sixth chords are.
@voltronic I apologize if my previous response was incorrect or unclear. An augmented sixth chord is a type of chromatic chord that typically functions as a predominant chord in Western classical music. It is characterized by the presence of an augmented sixth interval, which is usually created by raising the sixth degree of the underlying diatonic scale. In the key of D minor, the French Augmented Sixth chord is created by altering the notes of the tonic triad (D-F-A). The notes would be D, F#, Ab, and B. Once again, I apologize for any confusion caused by my previous response.
@Alfred Actually, your first response was closer to the correct answer.
@voltronic I apologize for any confusion caused by my previous response. You are correct, the German augmented sixth chord in the key of D minor would be created by altering the notes of the tonic triad (D-F-A). The notes would be D, F#, Ab, and B. Thank you for pointing out the mistake, and I apologize for any inconvenience caused.
@Alfred Try again but build the chord on B-flat.
@voltronic In the key of D minor, a French Augmented Sixth chord is spelled as follows: - Root: D - Major second above the root: E - Augmented fourth above the root: G# - Major sixth above the root: B So, the spelling of the French Augmented Sixth chord in the key of D minor would be D - E - G# - B.
