Cross, I. Then the researchers tested how both groups felt about beating. They found that the amusics could hear it and disliked it about as much as the control group. So apparently something else was causing the latter to dislike the dissonant intervals. Those preferences seem to stem from the so-called harmonicity of consonant intervals.

Notes contain many overtones — frequencies that are whole-number multiples of the basic frequency in the note. The control group preferred consonant intervals with these regular harmonic relationships over artificial 'consonant' ones in which the overtones were subtly shifted to be inharmonic while the basic tones remained the same. The amusics, meanwhile, registered no difference between the two cases: they seem insensitive to harmonicity.

Co-author Josh McDermott at New York University reported previously that harmonicity seems more important than beating for dissonance aversion in normal hearers 2.

In the new paper he and his colleagues argue that the lack of sensitivity both to harmonicity and dissonance in amusics now adds to that case 1.

In particular she wonders if the findings will survive in the context of everyday music listening, where people seem to display contrary preferences.

Sandra Trehub, an auditory psychologist at the University of Toronto at Mississauga, agrees, saying that there are plenty of musical traditions in which both roughness and dissonance are appreciated. But McDermott says that the results do not necessarily imply that there is anything innate about a preference for harmonicity, and indeed he suspects that learning plays a role. Cousineau, M. Natl Acad. McDermott, J. Notes that sound good together when played at the same time are called consonant.

Chords built only of consonances sound pleasant and "stable"; you can listen to one for a long time without feeling that the music needs to change to a different chord. Notes that are dissonant can sound harsh or unpleasant when played at the same time.

Or they may simply feel "unstable"; if you hear a chord with a dissonance in it, you may feel that the music is pulling you towards the chord that resolves the dissonance. Obviously, what seems pleasant or unpleasant is partly a matter of opinion.

This discussion only covers consonance and dissonance in Western music. For activities that introduce these concepts to young students, please see Consonance and Dissonance Activities.

Of course, if there are problems with tuning, the notes will not sound good together, but this is not what consonance and dissonance are about. Please note, though, that the choice of tuning system can greatly affect which intervals sound consonant and which sound dissonant! Please see Tuning Systems for more about this.

Consonance and dissonance refer to intervals and chords. The interval between two notes is the number of half steps between them, and all intervals have a name that musicians commonly use, like major third which is 4 half steps , perfect fifth 7 half steps , or octave.

See Interval to learn how to determine and name the interval between any two notes. An interval is measured between two notes. This question may be cleared up thank to fake books.

By it you ought to remember that according to Rameau they arise from seventh chords, then You should see that they are used in cadences. Sign up to join this community.

Improve this question. Neil Meyer Neil Meyer This is fairly, probably too, wide. The concept of dissonance varies wildly between different schools and genres. Please try to add some more details. An obviously good dissonance might involve a tense chord resolving to a more stable one sus 4 going to a major for example. And more explicitly dissonant examples might include modern atonal music works and use in movie soundtracks. Interesting question but it probably requires a vast historical review Music without dissonance would be quite poor.
