The Trio Con Brio ensemble in the Odeion School of Music (OSM) was crowned winners of the open category during the final round of the national SASMT Ensemble competition, which took place on 22 September 2021.  The Trio Con Brio comprises OSM students Kagiso Ramosa (clarinet), Maria Yasbeck (violin), and Karlin Kock (piano).

OSM lecturers, Drs Danre Strydom, Sharon de Kock, and Anneke Lamont served as instructors and mentors during the preparation phase. “The trio prepared their concert programme with an interesting methodology, by having weekly instruction from all lecturers individually on a rotation basis,” says Marius Coetzee, Artistic Director of the Odeion School of Music Camerata (OSMC). Elsabé Raath serves as the principal instructor. 

The OSMC took second place in the concert programme, while the instructor of the OSM Brass Quintet, George Foster, and the convenor, Quinn Kakora, were also selected to participate in the first round of the competition. Their recital was highly ranked and came third in the first round.

 SASMT competition develops young musicians 

The first SASMT Pretoria Ensemble Competition took place in September 2017. It would be the first competition of this nature to be held in the northern region of South Africa. The goal was to create an opportunity for young musicians to compete in groups, rather than focusing on solo performances. The feedback from the initial competition was overwhelmingly positive, culminating in the decision to make it an annual event.

The competition aims to develop young musicians through collaborative participation and by encouraging the enjoyment of performing with others. Another objective is to foster understanding, love, and appreciation for ensemble music and the performance thereof among young musicians.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
