Although [[225/128]] is often considered an augmented sixth rather than a minor seventh, in [[Meantone family#Septimal meantone|septimal meantone]] it is tuned identically to the [[7/4|harmonic seventh]], so the chord employing it may be considered a kind of [[dominant seventh chord]].
[[225/128]] is often considered an augmented sixth rather than a minor seventh, and especially in [[septimal meantone]] it is tuned identically to [[7/4]], so that the chord reduces to the much simpler [[4:5:6:7]]. However, chords employing it may still be considered a kind of [[dominant seventh chord]].
