exposed fifths

So-called hidden consecutives, also called direct or covered octaves or fifths, occur when two independent parts approach a single perfect fifth or octave by similar motion instead of oblique or contrary motion. A single fifth or octave approached this way is sometimes called an exposed fifth or exposed octave.

- An open fifth is a chord that contains the tonic, that's the first note, and the fifth note but no third. In the piano keyboard it would be the equivalent of playing middle C and G, and that's it. Open fifths give the impression of space, open spaces with lots of room to roam.

A hidden fifth occurs when an implied consonant passing note would create a parallel fifth. A hidden octave occurs when an implied consonant passing note would create a parallel octave.

What is the circle of fifths? The circle of fifths is a way to visualize the twelve musical keys and put them in a convenient order. It's used in music to help remember the notes that make up each key and group similar keys based on the notes that they share.

Parallel fifths are avoided between voices in a contrapuntal texture because they make it sound as if a voice has dropped out. The movement of voices in fifths (or octaves or fourths) in parallel sounds more like a single voices (and has been exploited as such in orchestrations and organ design.)

Parallel octaves and fourths Consecutive fifths are avoided in part because they cause a loss of individuality between parts. This lack of individuality is even more pronounced when parts move in parallel octaves or in unison. These are therefore also generally forbidden among independently moving parts.

The perfect 5th has the simplest form with the fewest peaks and valleys, making a smooth sounding tone. More peaks and valleys in a tone we will hear as a dissonance or "grinding" sound. The only thing smoother than the 5th would be an octave, or 2:1 ratio.

The Fifth Amendment creates a number of rights relevant to both criminal and civil legal proceedings. In criminal cases, the Fifth Amendment guarantees the right to a grand jury, forbids “double jeopardy,” and protects against self-incrimination.

Hidden fifths movement is when the voice are moving in the same direction, and the second interval is a fifth, but the first interval was something different. For example, the two voices moved from C & F (a fourth) to D & A (they both moved upwards into a perfect fifth).

Parallel octaves and fourths Consecutive fifths are avoided in part because they cause a loss of individuality between parts. This lack of individuality is even more pronounced when parts move in parallel octaves or in unison. These are therefore also generally forbidden among independently moving parts.

The 'rule of fifths' describes the ideal transverse proportions of the face to comprise equal fifths, each roughly equal to one eye width. The alar base width should be equal to the intercanthal width.

Bach did write such parallel octaves and parallel fifths occasionally. And guess what - they do not sound wrong. On the contrary, they sound just fine.
