A total of 650 children from the slum are now participating in the Ghetto Classics Orchestra.

Elizabeth Njoroge, founder of the orchestra, said the Korogocho slum is ranked among the most dangerous slums in East Africa.

Njoroge said she was tired of seeing children engage in crime due to unemployment and lack of school fees, adding that she started the facility to “give birth to the future Mozarts”.

She added: “Being here keeps the children out of crime and makes them become role models, if they stay out of crime and succeed that inspires other children to want to do the same.”

Kenyan local celebrities along with UN officials encouraged the young musicians armed with violins, guitars, trumpets, euphoniums, trombones and tubas among other instruments to continue on their journey of music.

Nelson Kimani, aged 15, told Anadolu Agency that he wants to be as famous as Mozart.

"I want a good future for myself and the future generations to come. At home, we are very poor but with my music I will change all that.

“I have met celebrities that I look up to, this has really motivated me," Kimani added.

Mohammed Yahya, UNDP’s Africa regional program coordinator, told Anadolu Agency youth unemployment in Sub-Saharan economies is high and is expected to worsen in the next few years as countries absorb nearly 90 million young people between the ages of 15 and 24 years into the job market.

As part of its 17 global goals for sustainable development, the UN has urged governments to end extreme poverty, unemployment and inequality affecting the young generation in order to save the planet.

“As the African youth population is projected to double by 2050, therefore, achieving the goals is a youth issue,” Yahya said.

He said that the youth from Korogosho slums, home to over 350,000 people and classified as the urban poor, need to be given the tools to change their country, which in this case is the art of music that will offer them employment.
