The Africans came to Callao in the 18th century to work in agriculture and extract gold. They brought their cultural identity to these lands and so they innovated again, managing to build another drum with some particularities different from the drum they had built in Trinidad and Tobago.

To achieve the almost perfect confection, they saw in the oak barrels that were used to store rum and wine or gunpowder, the perfect cylinder for the construction of the drum, then with remains of cattle leather or goat that cut to perfection they were able to tie to the barrel and this way the production of the first drums with which they executed the same calypso that they had already composed in Trinitarian lands was finished.

^{Wooden Bumbac, very similar to the first drums}

^{these drums tend to get out of tune so they are left in the sun to temper the leather and restore its musical properties.}

This means that the cultural transference remained intact during this voyage.

But the development of the Calypso in Trinidad and Tobago was not the same, there the drum was stylized and ended up becoming the current SteelDrum that first appeared in the 60's´s, metallic drum that was made thanks to the recycling of drums used to store hydraulic oil or petroleum derivatives. While in Venezuela the manufacture of Bumbac remained almost intact, the difference is that today synthetic leather is used as a membrane, since cowhide has to be tempered in the sun or with fire for tuning. And the wood is industrial veneer which undoubtedly gives a much lighter weight to the primitive drum.

The manufacture begins with the selection of wood veneer which is very light after cutting the wood is bent to hold it with aluminum rings so you can nail it easily and place the corresponding reinforcements that will give strength and will make the drum stay in the common cylindrical shape, also drilled the holes where the ring that presses the membrane.

All the elements are manufactured by Mr. Lugo, except the synthetic leathers that are trademarks known for use in battery. Thus we can notice that the modern manufacture of the drum is very simple in terms of manufacture. Once the drum is finished, it is painted in the color indicated by the person who orders it. Due to the country situation that crosses Venezuela currently only built by orders. In the past, 25 drums were made monthly, so says our friend Lugo.

The musical group Kaikó since its inception was designed as a fundamental objective to investigate, disseminate and project several popular Venezuelan rhythms being the Venezuelan calypso the most emphasized for being the most representative of the region.

The group has 4 record productions being the fourth recorded along with the group Junior Kaikó children's academic group thus manage to maintain a seedbed of new members who are taught to play the Caribbean genre.

Currently, the group Kaikó is investigating the instrument to give a specific musical tuning, this drum does not have a tuning like other instruments such as congas or timbales or the same battery which makes it very difficult to maintain an order in the different compositions that have made other groups in the region.

The factory not only manufactures drums Bumbac also manufactures other drums like cumacos, charrascas, drums of gaita.

Andreina Jaramillo is approximately 20 years old forming children through a non-profit organization that she founded with the name of Niños Cantores de Bellavista, Bellavista is the name of a community that has high rates of violent deaths and traffic of stolen cars, the idea of forming a musical group was to rescue children and move them away from violence and mafias through the sustained teaching of musical workshops.

In this way, Andreina has worked with more than 50 children and currently prepares a new generation.

^{Children learn by references from Andreina blow to blow .}

^{The Bumbac drum can be played sitting or standing depending on the occasion..}

The singing children not only learn to play Calypso, they also learn other musical genres of Venezuelan popular culture. Like the Parranda, Galerón, Joropo oriental in others. The music classes given by Andreina are completely free, and in some cases has the support of the government or private sector. Due to the economic situation in Venezuela, she often has to finance events for the children's performances.

^{Disease is not an obstacle for this brave man to learn to play..}

^{Children take music classes very seriously.}

The children who participate in Andreina's program are of scarce resources, a close bond has been maintained between the representatives and the organization, supporting them with their own resources.

At this time of school holidays, the organization actively organizes a plan of musical workshops for new members achieving the participation of 6 children, some of them already had knowledge about calypso, the central idea of this workshop is to attract new members for "the children singers of Bella Vista".
