perceptual transformation

the brain areas governing music and language/speech overlap

a person’s native tongue influences the way he or she perceives music

speakers of tonal languages such as Mandarin are much more likely than Westerners to have perfect pitch

nonverbal sounds such as music

some aspects of music engage the left hemisphere more than the right

the neural networks dedicated to speech and song significantly overlap.

This overlap makes sense, because language and music have a lot in common.
They are both governed by a grammar, in which basic elements are organized hierarchically into sequences according to established rules.
In language, words combine to form phrases, which join to form larger phrases, which in turn combine to make sentences.
Similarly, in music, notes combine to form phrases, which connect to form larger phrases, and so on.
Thus, to understand either language or music, listeners must infer the structure of the passages that they hear, using rules they have assimilated through experience.

In addition, speech has a natural melody called prosody.
Prosody encompasses overall pitch level and pitch range, pitch contour (the pattern of rises and falls in pitch), loudness variation, rhythm and tempo. Prosodic characteristics often reflect the speaker’s emotional state. When people are happy or excited, they frequently speak more rapidly, at higher pitches and in wider pitch ranges; when people are sad, they tend to talk more slowly, in a lower voice and with less pitch variation.
Prosody also helps us to understand the flow and meaning of speech.
Boundaries between phrases are generally marked by pauses, and the endings of phrases tend to be distinguished by lower pitches and slower speech. Moreover, important words are often spoken at higher pitches. Interestingly, some pitch and timing characteristics of spoken language also occur in music, which indicates that overlapping neural circuitries may be involved.

in 2009 medical anthropologist Kathleen Wermke of the University of Würzburg in Germany and her colleagues recorded the wails of newborn babies—which first rise and then fall in pitch—who had been born into either French- or German- speaking families.
The researchers found that the cries of the French babies consisted mostly of the rising portion, whereas the descending segment predominated in the German babies’ cries. Rising pitches are particularly common in French speech, whereas falling pitches predominate in German. So the newborns in this study were incorporating into their cries some of the musical elements of the speech to which they had been exposed in the womb, showing that they had already learned to use some of the characteristics of their first language.

When parents speak to their babies, they use exaggerated speech patterns termed motherese that are characterized by high pitches, large pitch ranges, slow tempi, long pauses and short phrases.
These melodious exaggerations help babies who cannot yet comprehend word meanings grasp their mothers’ intentions. For example, mothers use falling pitch contours to soothe a distressed baby and rising pitch contours to attract the baby’s attention. To express approval or praise, they utter steep rising and falling pitch contours, as in “Go-o-o-d girl!” When they express disapproval, as in “Don’t do that!” they speak in a low, staccato voice.

the melody of the speech alone, apart from any content, conveys the message.

… but after the six months of instruction, the children who had taken music lessons outperformed the others. Musically trained children may thus be at an advantage in grasping the emotional content—and meaning—of speech.

music lessons can improve the ability to detect emotions conveyed in speech (presumably through a heightened awareness of prosody).

that the language we learn early in life (e.g.: English, Vietnamese) provides a musical template that influences our perception of pitch.

pitch range of speech

Vietnamese and Mandarin are tone languages (words take on entirely different meanings depending on the tones with which they are spoken)
