Should I continue my classical study (avoiding parallel 5ths and octaves)?



Asked by: Lindsey George

Yes, keep up your studies. While you may not use some things directly, the principles can be useful. As mentioned in Dom’s comments, parallel fifths and octaves are avoided in order to keep musical lines independent.

Why should you avoid parallel fifths?





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.

How do you avoid parallel fifths and octaves?


Moving in the same. Direction by the same interval. Then be careful because that's when you're most likely to have trouble.

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.

Are parallel 5ths allowed?

Pretty much every theory course you will attend will probably refer to parallel or consecutive fifths as one of the greatest crimes you can commit in voice leading. The question however is why why are

Are parallel 6ths OK?





Parallel 3rds, 6ths, 4ths, and even tritones are all OK. Unisons (two parts sharing the same note) count as a kind of octave. Thus, these two instances are also bad. Sometimes students start to see parallels when there aren’t any, because they get confused as to which notes belong to which voice.

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.

Which instrument works the best with parallel 5ths?

Note that when using parallel fifths, the part that’s up a fifth should generally played on an instrument with a relatively “pure” tone, such as a flute.

Are direct octaves allowed?

A venerable rule of traditional Western part writing is the so-called Direct Octaves Rule (also known as Hidden or Exposed octaves), whereby similar pitch motion (i.e., two or more voices moving in the same direction) to a perfect octave should be avoided unless step motion is used.

Can you use 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.



What is hidden 5th?

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 are hidden fifths and octaves?

Again making the voices move in contrary motion helps to distinguish where the voices are going. Over the years many exceptions to the hidden fifth and octave rule have been introduced. Based on the
