The scales are sequences of repeated sounds of a system that regularly occur in ascending or descending order with respect to a single tone which gives its name to the entire scale.
Since the human can distinguish 240 different tones through eighth in the midrange of hearing, in principle could be used a great number of combinations to create tonal music.
However, Western classical musical compositions, folk and popular music and other musical traditions, using a relatively small number of scales that typically contain between five seven tones, researchers say.
The cause of this limitation is unknown, but in this study has shown that the components of the ranges of most of the scales used and extended in the history of music and all cultures are those with similar global spectrum with a series of harmonics.
These findings suggest that humans prefer the tonal combinations that reflect the spectral characteristics of vocalizations of our species, as well as highlight the spectral similarity between the scales used by different cultures. Conclusions
To study the emotional content of music, scientists at Duke have developed a database with about 1,000 melodies of classical music compositions and more than 6,000 folk songs, and then analyzed their tonal qualities.
On the other hand, we also asked 10 people who say isolated words with different tones of voice, or gave short monologues. The comparison of both records revealed the relationship between music and language. According
Purves says in the statement of Duke University, this research shows that there is a strong biological basis in the aesthetics of sound: Humans prefer music tonal combinations similar to those found in their speech.
This means that the main reason why we appreciate the music because it mimics our own speech, which was key to our evolutionary success. Purves said that "our appreciation of music is a happy byproduct of the biological advantages of speech and our need to understand its emotional content."
still unclear what came first in our species, if the song or the language, but scientists believe that "emotional communication in both spoken and music rooted in both cases non-linguistic vocalizations for expression of emotions. " Eco
