Can 16th notes cause parallel octaves?



Asked by: Jeremy Becker

Strictly speaking no, but occasionally you get away with it. In this case there are more problems than this one. The notes you have there are A#,C#,E, which is characteristic for the dominant on F#. So doubling the A# has some sort of doubling-the-third character.

Can you have parallel octaves?





A parallel octave refers only to two consecutive notes! If you have two or more instruments that are intentionally arranged to play the same voice (in unison or) one or more octaves apart, then you have octave doubling, which gives you a fat sound.

How do you avoid parallel octaves?

Avoid parallel fifths and octaves between notes following adjacent accents, if voices are 2:1 (second species). Allow if each of the notes forming the parallel is approached from a different direction. Allow if each of the perfect intervals is “unessential” (not part of the prevailing harmony).

How do you find parallel octaves?

One type of objectionable parallel is known as the parallel octave which is where you have two voices that start as an octave. And move in the same. Direction. In parallel to another octave.

Why do we avoid parallel octaves?

So composers of the 18th and 19th centuries avoided parallel fifths and octaves whenever their intention was to create independent voices (or melodies) sounded together.

Did Bach ever use parallel fifths?





Bach never intended to write parallel fifths in m. 7. Regarding BWV 248.23 (in G Major, not included in EMB), two different harmonizations of that melody appear in EMB (chorale numbers 323 and 324), but in 4/4 instead of 12/8 measure and in D and C Major respectively.

Are consecutive octaves allowed?

This is allowed, because the parts don’t change notes. Consecutive octaves are just as bad as consecutive 5ths. Consecutive octaves can sneak in just about anywhere, so always be on the look out for them! Check for consecutive octaves between all six voice pairings, as above.

Are parallel fourths okay?

Parallel fourths (consecutive perfect fourths) are allowed, even though a P4 is the inversion and thus the complement of a P5. The literature deals with them less systematically however, and theorists have often restricted their use.

How do you fix parallel 5ths?

Then you can set about repairing. Them sometimes changing the chord is the answer. Sometimes just changing the inversion of the chord will help you but thinking about this bit of polarity.

How do I get rid of parallel fifths?

So how do we avoid consecutive fifths. The answer is we avoid writing two cards that are next to each other in the same inversion.



What is a contrary 5th?

What is a hidden octave?

: an unsounded musical interval of an octave that is implied by the similar up or down motion of two voice parts and that if sounded would produce consecutive octaves.



Can you go from a fifth to an octave?

To answer your original question: It depends. If you use similar motion in going from the fifth to the octave, that’s a non-no. Doing what you did in the example, maintaining one note of the fifth in the following octave: that’s OK, but not ideal.

Are there 12 notes in an octave?

In the western musical scale, there are 12 notes in every octave. These notes are evenly distributed (geometrically), so the next note above A, which is B flat, has frequency 440 × β where β is the twelfth root of two, or approximately 1.0595. The next note above B flat, which is B, has frequency 440 × β 2.
