For instance, the above-mentioned C major scale contains the tritones F–B (from F to the B above it, also called augmented fourth) and B–F (from B to the F above it, also called diminished fifth, semidiapente, or semitritonus); [2] the latter is decomposed as a semitone B–C, a whole tone C–D, a whole tone D–E, and a semitone E–F ...
Augmented fifth. In Western classical music, an augmented fifth (Play ⓘ) is an interval produced by widening a perfect fifth by a chromatic semitone. [1][3] For instance, the interval from C to G is a perfect fifth, seven semitones wide, and both the intervals from C ♭ to G, and from C to G ♯ are augmented fifths, spanning eight semitones.
Conversely, no augmented or diminished interval is diatonic, except for the augmented fourth and diminished fifth. A ♭-major scale. The distinction between diatonic and chromatic intervals may be also sensitive to context. The above-mentioned 56 intervals formed by the C-major scale are sometimes called diatonic to C major.
A major fourth (Play ⓘ) is the interval that lies midway between the perfect fourth (500 cents) and the augmented fourth (600 cents) and is thus 550 cents (F). It inverts to a minor fifth. Wyschnegradsky considered it a good approximation of the eleventh harmonic [1] (11:8 or 551.32 cents). [2] A narrower undecimal major fourth is found at ...
This contrasts with equal temperament, in which intervals with the same frequency ratio can have different names (e.g., the diminished fifth and the augmented fourth); and with other forms of just intonation, in which intervals with the same name can have different frequency ratios (e.g., 9/8 for the major second from C to D, but 10/9 for the ...
The Lydian scale can be described as a major scale with the fourth scale degree raised a semitone, making it an augmented fourth above the tonic, e.g., an F-major scale with a B ♮ rather than B ♭. This mode's augmented fourth and the Locrian mode's diminished fifth are the only modes to have a tritone above the tonic.
Quintal harmony (the harmonic layering of fifths specifically) is a lesser-used term, and since the fifth is the inversion or complement of the fourth, it is usually considered indistinct from quartal harmony. Because of this relationship, any quartal chord can be rewritten as a quintal chord by changing the order of its pitches.
This triad is consequently called the supertonic diminished triad. Like the supertonic minor triad found in a major key, the supertonic diminished triad has a predominant function, almost always resolving to a dominant functioning chord. [7] If the music is in a minor key, diminished triads can also be found on the raised seventh note, ♯ vii o.
