Umakhoyane
Umakhoyane: Indigenous South African instrument affiliated with the Zulu tribe.

According to Dr Absolum Nkosi, Senior Lecturer in the Odeion School of Music at the University of the Free State (UFS), “ancient traditional instruments form part of the African heritage”. As such, with Heritage Day upon us, it is imperative to highlight these South African indigenous musical instruments. 

Some of the most prominent South African musical instruments currently in the possession of the UFS, include uhadi and umakhoyane, also referred to as ugubhu. At first glance, one would think that these instruments are the same. This would not be an incorrect assumption. In fact, these instruments share similarities in terms of purpose and how they have been used throughout their existence. 

Similarities and differences between the instruments
For instance, both uhadi and umakhoyane (ugubhu) are instruments traditionally played by women. Dr Nkosi maintains that songs accompanied by any of these instruments are usually personal, as they cover topics such as love, family, and relationships. Furthermore, the songs that were sung with the assistance of these instruments, were also about a reflection of the individual’s mental state. As such, the fact that both instruments have a very soft sound aided in that reflective process. 

However, there are key variations between these instruments. Uhadi is a single-string acoustic bow affiliated with the Xhosa tribe, whereas umakhoyane is a single-string acoustic bow affiliated with the Zulu tribe. In addition, umakhoyane possesses a bridge in the middle that uhadi does not. Furthermore, there is also a difference in the sound produced by the two instruments. “Uhadi produces one sound when it is played with the string openly without touching it; you can then get the second sound by pinching and releasing the string using the index finger and a thumb. However, umakhoyane produces two notes when playing the string on the upper and the lower level. The bridge in the middle of the string divides it into an upper part (low tone) and a lower part (high tone),” Dr Nkosi indicated.  

It is imperative to note that these instruments have adapted over time. In fact, they have been used in genres such as Jazz and contemporary Afro music. Therefore, Dr Nkosi believes that the preservation of these indigenous instruments is essential, as it keeps the African musical identity alive.

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.
