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.

Nanoscience, which is revealing new properties of very small arrangements of atoms, called nanoparticles, is opening a new world of possibilities. The Department of Physics at the University of the Free State is undertaking fundamental research with potential commercial applications. Its equipment and expertise is giving solid state physics research the edge in South Africa.

The UFS team of researchers and students are passionate about studying planets and atoms, all under one roof. Recently, the department, in collaboration with the South African Agency for Science and Technology Advancement (SAASTA), hosted a nanotechnology facility tour to give the public, learners and the media the opportunity to familiarise themselves with the science of nanotechnology, its origins, potential applications and risks.

Successes of the department
According to Prof Hendrik Swart, Senior Professor in the Department of Physics, the increase in resources since 2008 is playing a big role in the success rate of its research outputs. The Sarchi Chair awarded to Prof Swart in 2012 (bringing with it funding for equipment and bursaries) also contributed to the successes in the department.

The UFS Directorate Research Development also availed funding that was used for bursaries. These bursaries made it possible for the department to appoint 10 post-doctoral fellows, not one of them originally from South Africa.

The investment in people and equipment resulted in researchers and students publishing some 80 articles in 2016. Their work was also cited more than 900 times by other researchers in that year.

Another highlight in terms of the department’s growth in the past 10 years is the new wing of the Physics Building. Physics at the UFS is the only place in sub-Saharan Africa where state-of-the art equipment is found under one roof.

Application of research
The department is a unique research facility with equipment that includes the X-ray Photoelectron Spectrometer (for the study of atoms), the Scanning Auger Microscope, as well as the Ion Time-of-Flight Secondary Ion Mass Spectrometer (revealing the chemical bonds in a sample, and drawing maps of the positions of atoms).

One of the areas on which the department is focusing its research, is phosphors. Researchers are exploring light emitting diodes (LEDs) which use less energy, are brighter and provide a wider viewing field. They are also looking into LED displays (LCDs) which are used in flat screens – the phosphors create the different colours and backlighting.

The research on solar cells reveals that phosphors can increase their efficiency by increasing the range of light frequencies which can be converted into electricity. Glow-in-the-dark coatings absorb light in the day and emit it later so cells can charge at night. As glow-in-the-dark phosphors become cheaper and more effective, they can be used as a lighting substitute on the walls of houses, street numbers and stop signs.
