JOHAN SUNDBERG, biography

Standard

Johan Sundberg

Johan Sundberg (born in 1936, Ph.D. in musicology Uppsala University 1966, doctor honoris causae 1996 University of York, UK) had a personal chair in Music Acoustics at the department from 1979 to his retirement 2001. Since 2002 he is Visiting Professor at the University of London, UK.

He early became interested in the acoustical aspects of music, starting with a doctoral dissertation work on organ pipes. After the dissertation, singing voice and music performance have been his main research topics. He was the head of the music acoustics research group from 1970 to 2001. He has supervised or co-supervised 17 doctoral dissertations, 7 in medical faculties.

In Musikens Ljudlära Sundberg presents music acoustics in popularized form to the interested layman. The book Röstlära, 3rd edition 2001, presents an overview of research on the singing voice. As the President of the Music Acoustics Committee of the Royal Swedish Academy of Music, Sundberg was editor or co-editor of twelve volumes in a series of proceedings of public seminars on music acoustic themes arranged in Stockholm since 1975.

Sundberg has also had extensive experience of performing music. For 24 years he was a member of the Stockholm Bach Choir, 9 years as its president. He has studied singing for Dagmar Gustafson and made his public debute with a Lieder recital on his 50th birthday. He is a member of the Royal Swedish Academy of Music, of the Swedish Acoustical Society (President 1976-81) and a fellow of the Acoustical Society of America.

I’m a research fellow at the Max-Planck-Institute for Evolutionary Anthropology in Leipzig, Germany. There I’m basically working on phonetics and phonology of a number of languages, especially from the Caucasus, Siberia, India, Southern Africa and Argentina. But recently I started doing research on the phonetics of human primates (chimps & bonobos).

What am I doing?

In general …

  • I’m eager to learn about modelling language change driven by language contact, social structures and geography
  • I’m deeply interested in voice, voice perception and voice production from an evolutionary, behavioral and cultural perspective
  • I’m deeply interested in the mechanisms of sound change and language involving acquisition, learning and accommodatin
  • I enjoy doing field work e.g. in language documentation projects, and such engaged in documenting endangered languages
  • I’m eager to learn more about specific phonetic details in individual languages, such as
    • Ket (Yeniseic, Central Siberia)
    • Tsez, Bezhta, Hinuqh, Dargi, Lezgi, Chamalal, Avar, Chechen, Ingush (Nakh-Dagestanian, North-East Caucasus), Georgian (Kartvelian),
    • Gta’, Bonda (Munda, India)
    • Hoocaak (Sioux, USA)
    • German (especially Thuringian-Saxonian varieties)
    • Taa (Tuu (KhoiSan))
    • Kurmanji Kurdish (Iranian, Turkey/Armenia/Iraq/Azerbaidjan/Iran/…)
    • Yoruba (Niger-Kongo), Oko, Ebira (Atlantic-Congo)
    • Vilela (Lule-Vilela)
    • Welsh (Celtic)

Normalized Spectrum for easy comparison of relative harmonic intensity in Overtone Analyzer

Video

Published on Apr 11, 2013
This video shows how to compare the relative intensity of the harmonics in a recording with the new normalized spectral display in Overtone Analyzer. Instead of showing the absolute intensity in the spectrum, each point in time is scaled so that the loudest harmonic at that point has zero decibel, and the intensity of all other harmonics is relative to the loudest one. This makes it easier to visualize the spectral composition and the timbre of the sound.

The overtone singing is done by Wolfgang Saus (http://www.oberton.org), and the software is Overtone Analyzer (http://www.sygyt.com).

Comparing sounds with Overtone Analyzer (Part 2)

Video

Published on Aug 14, 2013
Comparing sounds and audio recordings with Overtone Analyzer Premium. This tutorial shows the Long Term Average Spectrum (LTAS), and how to display the LTAS of several marked sections on top of each other so that they can easily be compared.
The video also shows the Normalized Spectrum, which allows to analyze the relative harmonic intensity of a recording.
These features are only available in Overtone Analyzer Premium, not in the Live or Free Edition.

Overtone Analyzer Quickstart Tutorial: record and visualize your voice

Video

Ajoutée le 10 mars 2013
This is a video version of the quickstart tutorial for Overtone Analyzer that can be found at http://www.sygyt.com/en/quickstart. The video explains the basic features of the software and how to use them to record and visualize your voice or instrument.

In particular, I’m showing you to set up your microphone, how to make a recording, how to play it back and listen to it, how to visualize the fundamental pitch, the spectrum, and the spectrogram, how to apply frequency filters to listen to individual overtones, and how to use the overtone sliders.
