In your case, both voices are inner voices, the the octave is allowed, and in fact is completely normal. 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 an octave and a fifth?
In classical music from Western culture, a fifth is the interval from the first to the last of five consecutive notes in a diatonic scale. The octave of the fifth is the twelfth.
What is a hidden fifth music?
: an unsounded musical interval of a fifth that is implied by the similar up or down motion of two voice parts and that if sounded would produce consecutive fifths.
What are 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.
Are parallel fifths bad?
In this style, known as the Common Practice Period, parallel fifths and octaves tend to leave a blank space, or a gap, in the musical texture (the overall sound) as if a voice has disappeared. This is why, in this context, parallel fifths are bad.
Are fourths and fifths the same?
Everyone’s right! You can use “fourths,” “fifths,” “circle,” “cycle” — it’s all the same thing!
What is a fourth and fifth in music?
In music, major fourth and minor fifth are intervals from the quarter-tone scale, named by Ivan Wyschnegradsky to describe the tones surrounding the tritone (F♯/G♭) found in the more familiar twelve-tone scale, as shown in the table below: perfect fourth. major fourth. tritone.
Why are parallel fifths not allowed?
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.
Why do octaves and fifths sound consonant?
The octave, fifth, and fourth are the intervals which have been considered to be consonant throughout history by essentially all cultures, so they form a logical base for the building up of musical scales. A typical strategy for using these univerally consonant intervals is the circle of fifths.
What are exposed octaves?
Why do we not use consecutive fifths in music?
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.
What do you call a single fifth of an octave?
A single fifth or octave approached this way is sometimes called an exposed fifth or exposed octave.
Why are fifths and octaves written in parallel?
The intervals of a fifth and an octave create a distinctive ‘bare’ sound. If they are written in parallel attention is drawn to this bareness, even if there are other voices in the texture. Early sacred vocal music involved a lot of parallel motion between voices, particularly in fifths and octaves.
Hidden or exposed fifths and octaves The sensitivity to parallels in the simple texture of Bach’s chorale style means that even similar motion to a fifth or octave can give the impression of parallels. The example below explains these ‘hidden’ or ‘exposed’ octaves- the same can happen with fifths.
