A progression that uses diminished sevenths and these chords to execute a chain of modulations is called the “Devil’s Mill” or the “Omnibus.” (15[1])The theory that these chords are “double-diminished” implies that their typical highest note is the root, and their typical bass note is the double-flat third. The half-diminished Tristan chord is often analyzed (-5[1])as one of these (15[1])chords with a G-sharp appoggiatura. (-5[1])So-called (-5[1])“Mozart fifths” that arise when resolving a (*) type of these chords can be avoided by inserting a cadential six-four chord before the dominant. The characteristic interval of these chords resolves chromatically outward to an octave. In C major, one of these chords contains an A-flat, C, (10[1])F-sharp, and either E-flat, D, or no fifth. For 10 points, what chords come in German, (10[1])French, (10[1])and (-5[1])Italian (-5[1])varieties? ■END■ (10[3]0[5])
