How to define “simple” when considering consonance and interval ratios?



Asked by: Kimberly Rodriguez

What interval is sometimes considered consonant and sometimes considered dissonant?





A major second (e.g. the notes C and D played simultaneously) would be considered dissonant if it occurred in a J.S. Bach prelude from the 1700s; however, the same interval may sound consonant in the context of a Claude Debussy piece from the early 1900s or an atonal contemporary piece.

What intervals are perfect consonance?

The simple intervals that are considered to be consonant are the minor third, major third, perfect fourth, perfect fifth, minor sixth, major sixth, and the octave. In modern Western Music, all of these intervals are considered to be pleasing to the ear.

What is difference between consonance and dissonance?

consonance and dissonance, in music, the impression of stability and repose (consonance) in relation to the impression of tension or clash (dissonance) experienced by a listener when certain combinations of tones or notes are sounded together.

Is the 4th interval consonant?

The fourth is always consonant when supported by a lower third or perfect fifth, for example, E-G-C-E is consonant, but G-C-E is dissonant. In more contemporary music, many consider the fourth to always be as consonant as the fifth.

How do you identify consonance in music?





Consonant musical sounds are often described with words like “pleasant”, “agreeable”, “soothing”, and “melodious”. In other words, notes that sound comfortable when played together are considered consonant.

What’s an example of consonance?

Consonance is a figure of speech in which the same consonant sound repeats within a group of words. An example of consonance is: “Traffic figures, on July Fourth, to be tough.” Some additional key details about consonance: Consonance occurs when sounds, not letters, repeat.

What is a perfect consonance?

Consonant Intervals in Tonal Music



The perfect fifth and the perfect octave are considered perfect consonances. The unison is a consonance insofar as it can be considered an interval at all (many say it cannot). ∙ The major third and sixth, as well as the minor third and sixth, are imperfect consonances.

What is the interval?

An interval is a range of numbers between two points, which are also numbers, and all the numbers in that range.. It can also be called a set of numbers between two points.

What is the most common interval?

The most common enharmonic intervals are the diminished fifth and the augmented fourth, shown below. These two intervals divide the octave into two equal parts. These intervals contain three whole steps, for this reason these intervals are referred to as the tritone.



How do you find the interval ratio?

In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth (for example C to G) is 3:2 ( Play (help·info)), 1.5, and may be approximated by an equal tempered perfect fifth ( Play (help·info)) which is 27/12 (about 1.498).

Why are intervals called perfect?

Perfect Intervals



These intervals are called “perfect” most likely due to the way that these types of intervals sound and that their frequency ratios are simple whole numbers. Perfect intervals sound “perfectly consonant.” Which means, when played together, there is a sweet tone to the interval.

What is the difference between a major and minor interval?

A minor interval has one less half step than a major interval. A minor interval has one less semitone than a major interval. For example: since C to E is a major third (4 half steps), C to Eb is a minor third (3 half steps).



How do you tell if an interval is Major Minor augmented or diminished?

Augmented intervals are one half step larger than perfect or major intervals and diminished intervals are one half step smaller than perfect or minor intervals.

How do you find intervals quickly?

Remember that we always start with a lower note and treat it as the tonic or the first note of the scale. This time F is the lower note.

How do you tell if a third is major or minor?

Third. Major third and this one here you might be able to guess an alternative to a major third one semitone smaller with three semitones is a minor.
