The Deutschlandfunk Kultur broadcasts on Thursday, 28 February 2019 from 22h to 22h30 a radio feature about the European Overton Choir. The EOC is an experimental project choir that once a year from Easter Monday invites interested singers for a week to experiment with the potential and new sound possibilities of overtones in choral music. Works will be sung by notes as well as improvisations developed with new methods.

European Overton Choir, next project week 22.-28. April 2019

Stuart Hinds from the USA is undisputedly the star of polyphonic Western overtone singing. No one else handles two melodies in basic and overtone with such virtuosity. He is also one of the most productive composers for overtone singing and has written several pieces for solo and choral singing.

Now he has written a new book “Making Music with Overtone Singing” in 2017. It is a systematic learning aid that allows every slightly advanced overtone singer to get into the art of polyphonic overtone singing.The new book starts where overtone beginners begin to control their tones and leads from there into the complex polyphony. The book thus forms the bridge to his more demanding 15 songs.

His sheet music book “An Overtone Expirience – 15 polyphonic overtone songs you´ll love to sing”, published by Traumzeit-Verlag in 2012 and translated by me, required advanced overtone singing experience.

Stuart Hinds generously makes his book available as a free PDF download. In addition to the book, the download also contains sound samples sung by the author.

In November 2016 Dorothea Sahlmüller interviewed 33 voice experts for an online voice conference (affiliate link). 33 video contributions illuminate the human voice from 33 highly exciting and sometimes unusual perspectives.

I was interviewed too. My video was even voted on number 2 of the best interviews :) You will learn some phenomena that you would not immediately associate with overtone singing. Among them a new hearing test that will fundamentally change your perception of sound, experiences with dolphins and overtone singing in the Red Sea and my emotional experiences with autistic children.

The congress package with all the videos and some extras can be downloaded from Dorothea’s website.

Many singers today make sound recordings at home. Grammy-award winning record producer, audio engineer, recording artist, and educator Prince Charles Alexander offers students a first-hand opportunity to learn the technologies behind vocal production.

Free online course about the recording environment, microphones, equalization, compressors, A-D-A conversion, the listening environment, human perception, natural widening concepts, artificial widening concepts, reverb, delay, and more.

I’m just taking the course myself, working through the archived material, is worth it!

Zurzeit (März 2014) unterrichte ich in Schweden und genieße den nordischen Frühling. Zum Anlass zweier Konzerte am kommenden Wochenende in Lund und in Kopenhagen habe ich einen Satz des schönen schwedischen Volksliedes “Ack, Värmeland, du sköna” für Obertongesang geschrieben, der dort zur Uraufführung kommt. Zusammen mit Anna-Maria Hefele singen wir eine Version für zwei Stimmen und Nyckelharpa.
