Crying of newborn babies: A sign of inborn musical skill?

Even the crying of newborn babies seems to be more musical than we think. This can be concluded from an interesting study that was published last month in Current Biology. German researchers were able to show that newborns don’t just cry randomly, but - when studying the audio signal of their crying - one can distinguish between French and German babies. The German babies - only three days old - cry in a downward fashion, their French contemporaries showed an increasing swelling of the cry and stop abruptly.

Sound example: German & French baby cries.

How can we explain these differences? Babies do hear about three months before they are born. And the few prenatal studies that are available show that babies, in that stage of their development, already perceive and remember sounds. For instance, they recognize the sound of their mothers voice just after birth, and they can distinguish between tunes that they heard during pregnancy from those that they have never been exposed to before.

The correlation between the mother language of the babies and their average crying pattern, suggests that exposure to the language spoken by their caregivers (mother, father, etc.) influences the crying, since French language, on average, consists of raising melodies, and German intonation often shows a decreasing shape. The researchers suggest that this as a sign of a sensitivity to language from very early on in life.

My interpretation would be different. I would not so much relate these results to language, as well as a sign of a high sensitivity to the musical aspects of speech: rhythm, melody, stress (i.e. prosody). As quite some studies have shown (e.g., authors like Fernald, Trehub, Trainor, and others), infants and young children are extremely sensitive to these 'musical' variations in their environment. For example, infants seem to be highly sensitive for the musical and emotional aspects of infant-directed speech (IDS), more so than the actual linguistic structure, let alone semantics. I would therefore claim the results of the baby-study are actual evidence for very early signs of musical sensitivity to intonation and other musical aspects of sound, than that it should be seen as evidence for the start of learning a language.

P.S. I describe this argument in length in my new book Iedereen is muzikaal (Only available in Dutch).

A gene for music?

Last week a paper was published in PLoS-ONE suggesting a relation between AVPR1A-Haplotypes and musical creativity. A group of Finish researchers analyzed 19 families with a total of 343 family members on their musical aptitude —using the Seashore test and a test developed by one of the authors— and their DNA profiles. They were able to show an association between these and related genes and levels of musical creativity. The research contrasts earlier research with twins that suggested no such relation (e.g., Coon & Carey, 1989). The authors propose the interesting hypothesis that music perception and creativity in music are linked to the same phenotypic spectrum of human cognitive social skills, like human bonding and altruism, both associated with AVPR1A. Music as a form of ‘extreme’ bonding behavior...

It was just a matter of time for such a study to emerge. Still, the results of this study are merely correlational. I like to think of the capacity for music as shared instead of being special, and a result of complex nature and nurture interactions.

How well would you do as an expert?

In the Netherlands (and I’m sure there are versions of it in the UK and the US as well) there is a weekly radio show containing a returning item in which music experts are asked to compare and judge two or three CD recordings of the same piece, without knowing who the musicians are. They have to guess the performers and describe why they do (or don’t) like that particular performance.

How well would you do in such a test? The common hypothesis is that experts do this much better, e.g. under the assumption that they are more sensitive in their listening skills. But do experts indeed hear more detali and more nuances when compared to a 'common listener'? Or do they just have more terminology available to verbalize these differences?

Two years ago our group did a large-scale online listening experiment with a similar task. Participants were asked to compare several pairs of recordings of well-known musicians. One of the recordings was taken directly from a CD, but the other was originally performed at another tempo (faster or slower) and then scaled to be similar in tempo to the former recording. The task was to judge which recording was real and which one was manipulated, by focusing on the timing used by the performer.

To give you an idea of the difficulty of the task, below an example.

The results were recently published in the Journal of Experimental Psychology, with a surprising outcome: the judgments seem to be largely influenced by exposure to music (listening a lot to one’s favorite music) and not (at all) by the level of expertise (amount of formal musical training). One seems to learn a lot by simply listening.

* The first recording is the original. It is Glenn Gould performing English Suite No. 4 by J.S. Bach. The second recording is Sviatoslav Richter performing the same piece. However, this recording was sped up from 70 to 87 bpm making his use of tempo rubato 'unnatural'.
