Quell-Klang - Contemporary App Music @Berlin Cathedral 6|6|2013

Описание: "Quell-Klang" by Daniel Grote is a composition that plays around with timbre and its components: partials. Regarding to the model of partials, the difference between the tone color of a trumpet and the sound of a violin depends on the number and the volume level of partials that constitute the sound. The idea of "Quell-Klang" is not only to create entirely new tone colors, but develop melodic and harmonic phrases within a piece: a Klangfarbenmelodie.

Five musicians play the fundamental note und its first eight partials. It is when they play collectively, that a musical composition evolves: Following a graphic musical score, "Quell-Klang" constantly bears changing acoustic colors and unconventional harmonies. The following video shows a few moments out of the four minute long piece.

To create individual sinusoidal tones and level their volume we used the App "ThumbJam". "Beatmaker2" helped us to sample those tones, which we then controlled with a self-programmed Interface via the App "Beatsurfing".

Today, we have the technological possibilities to create and alienate complex sounds on devices that we use in every-day life: digital devices as smartphones. Our approach to consciously reduce the range of tones to its basic components (partials) offered us a variety of different opportunities to compose the piece. No need to say that even during the process of composing "Quell-Klang", lots of different ideas came to our minds. Let yourself be inspired by this approach and create your own "Klangfarbenmelodie".

-- Anniversary Concert at Berlin Cathedral on 6|6|2013
The DigiEnsemble's performance of Bach's Christmas Oratorio played on mobile devices only at the Berlin Cathedral in 2012 was a huge success. In celebration of the Berliner Dom's 20 year anniversary, the cathedral's organist Andreas Sieling and the DigiEnsemble paired up and gave their first concert together on June 6, 2013.

For the anniversary show, the musicians composed four pieces. Their intention was to experiment with the sound possibilities of the cathedral's interior architecture. They used 12 loudspeakers, placed all around the cathedral, and created new sounds as "frozen echoes" and "fluid music" (rainshower in the dom).
