    I specialise in beachcombing the scholarly journals and university websites for uncommonly intriguing academic articles by uncommonly intriguing...

    The first scientific study to employ real-time magnetic resonance imaging  (RT) MRI to obtain midsagittal vocal tract sequential image data from a total of 5 soprano singers was published in the Journal of the Acoustical Society of America, November 2010 (Express Letters pp. EL335-EL341)

    Erik Bresch and Shrikanth Narayanan from the University of Southern California asked the singers to perform a two octave musical scale (hitting the notes as best they could considering the constraints of having their head inside a very noisy MRI machine)

    The digitised recordings showed that the sopranos were producing their notes in ways which were “well in accordance with the expectations” (backing up previous soprano voice research results obtained by other experimental methods).

    Rather than leading to a full comprehension of soprano voice production techniques, however, the new study instead called into question whether sopranos might all be singing in exactly the same way – perhaps hinting at opportunities for further research?

    “… based on our study, we cannot conclude that all sopranos employ generalizable strategies for resonance tuning the way it has been described in prior literature.”

    The paper can be read in full here : Real-time magnetic resonance imaging investigation of resonance tuning in soprano singing.


    On seeing the title, I wondered at first if “Sopranos” referred to the TV show.

    However, I am glad it turned out to be about the voice.  Looking at the paper, I read
    trained in Western opera and who were native American English speakers.
    It would be interesting if there were systematic differences with native speakers of other languages, especially the operatic ones such as Italian, and with soprano singers in other genres, perhaps those that get to the later stages of American Idol or X Factor USA.
