Zulu Musical Instruments, Essential To Develop Musical Traditions In Africa

African music is the music of Africans who live in a large region of 50 nations, each with a special culture, history and language, South of Sahara. Zulu musical instruments are part of this multilingual culture. African music has some distinct characteristics: the use of repetition is one of them. Another important characteristic is the polyphony; this is the combination of different musical parts played simultaneously.

The history is marked by the awesome military strategies of the Zulu King Shaka. The King’s and his warriors’ campaign of expansion is well known in world history. Zulu rich traditional culture includes songs, dances and colorful rituals, Zulu musical instruments are spectacular and original. A variety of Zulu musical instruments are well known, s well as the traditional Mine dance; Zulus have longtime used their music as a cry for freedom.

African music is really rich in modes of expression: drum ensembles are using Zulu musical instruments from the percussion family. Each drummer uses special methods to produce sounds to distinguish his drum from the others. Iron bells are very popular Zulu musical instruments; they are used to produce a repeated sound to help the drummers to play at the correct time.

Zulu musical instruments, rare and very special
The akadinda is a king of xylophone; two groups of African musicians are playing simultaneously. The first group is playing repeatedly the same pattern; the second group plays to fill in the missing sounds. Groups of Zulu musicians play also using flutes, trumpets or xylophones. Each player plays a single note in a strange rotation with the other players. The result is a polyphonic piece, characteristic to African music.

Musical practices of South African people were observed from many years; Zulu musical instruments are obsolete. Venda mbila is an old Zulu musical instrument; it is not used anymore. Reed flutes, contrary, are still very popular. The influence of foreign cultures and civilizations causes many of old Zulu musical instruments to become obsolete.

Musical instruments such as tsonga a horn, ingungu a friction drum, nkoka a drum, pedi a flute, venda musical bow and stick, deze and demba thumb piano and resonatos, umfece ankle rattles are almost obsolete.

To preserve this awesome heritage of Zulu musical instruments, the necessary information was entered into a database; each Zulu musical instrument was digitally photographed to preserve all information about it.

Use of Instrument browser

In this part of tutorial we shall demonstrate work of the grid with large data volumes on the example of Instrument

browser.

The business model already contains Instrument class. We shall add only one field (quoting currency) and create a lot of instruments in the application (e.g. 100000). For this purpose we shall modify Provider class and create an arbitrary list of instruments. As before, this list will be available as follows. Now let’s bind the grid to the data source. Memory consumption is one of the most important aspects of displaying large data volumes. When grid connects directly to application business logic, it significantly reduces memory consumption because there are no intermediate objects between the data layer and its presentation.

Let’s create InstrumentBrowser control and place it at the main panel. We shall add a panel for instrument filtering and

searching and the grid to this control. We shall configure grid in the designer and link it to the data source.The screenshot below demonstrates the results of application work.

Let’s note an important detail. The collection of instruments contains about 100,000 elements. It is created when the application is launched. Total memory consumption of the entire application is about 45 MB. This collection is bound to the grid when Instrument browser tab is opened. After that, memory consumption increases to 59 MB. This means that the grid uses about 14 MB to display 100,000 elements. This amount of elements loads for about seconds.These indicators demonstrate of grid performance with realistic numbers of instruments.

To navigate large data volumes a high performance filter is required. The grid provides a simple API for filter implementation. In this application many instruments have Weight, Shares, Capitalization values equaling 0. For more convenient data interpretation it is better not to display insignificant zeroes. Besides, it is better to add thousand separators for data formatting. Use of formats is the simplest way to implement this functionality. An example of creating a simple format for displaying digital information is provided below.

Net Grid provides broad functionality of displaying various datagrid elements, such as cells, rows, headers and columns. The main objective of Dapfor is to develop high-performance software, specifically grids. Popular MVVM programming model that extensively uses databinding, data gridview to separate data from presentation.

You might argue that manual insertion is possible than why the need for an autosampler? Well, it helps in time-optimization and reproducibility as well.

While buying autosamplers for your HPCL instrument, you need to keep in mind some points which are briefly discussed as under-

Begin by asking how many samples actually you need in your laboratory on a periodic basis. If you analyze thousands of samples, then investing in autosampler is a great idea! On the other hand, if you deal with limited samples, a manual injector does the needful for you at a lesser price. However, if you prefer accuracy than the cost-factor, autosamplers offer amazing results. Once you have dealt with this point, its now the time to ask what exactly are the size of samples that you need to analyze. It is a proven fact that autosamplers are far more efficient than human beings. Investing in an autosampler is a good idea even if you have to deal with low-volume samples in your laboratory.

After having analyzed these points, you need to know how fast your instruments cycle time and the sample loading speed are. It is worth considering these points in case speed is important to you. It is very much crucial to choose the right supplier when you are buying an HPLC autosampler. Find out the kind of services, support the supplier offers including warranty.
