Early Life & Education

Harmonize, born Rajab Abdul Kahali on March 15, 1991, hails from Mtwara, Tanzania. Growing up in a modest household, he faced the challenges that come with limited means, as his parents parted ways during his formative years. His father, Mzee Konde, and his mother, Mrs. Konde, influenced his journey.

Amidst the ebb and flow of existence, Harmonize triumphed over adversity, emerging as a beacon of inspiration. His secondary education culminated at Mkundi Secondary School in 2009, a milestone in his pursuit of knowledge and self-discovery. Determined, he set his sights on the dynamic cityscape of Dar es Salaam, where the harmonious cadence of his dreams beckoned.

Like a spirited wanderer, Harmonize ventured into the vibrant tapestry of the city’s streets, navigating the deep pulse of Kariakoo Market. Immersed in the ebullience of daily life, he donned the mantle of a street hawker, guided by an unyielding passion for music and the unspoken symphony of his soul.

The fickle winds of destiny whispered their secrets in 2013 as Harmonize was embraced by the prestigious WCB Wasafi Record Label. This fortuitous alliance set the path to his musical future ablaze, catapulting him to previously unimagined heights.


Harmonize, a musical virtuoso whose soulful melodies resonate through the vibrant streets of Dar es Salaam, embarked on a path paved with harmony and adversity. Immersed in the rhythmic tapestry of life, he embraced an eclectic array of odd jobs to fuel his artistic fire, his unwavering passion serving as a compass amidst the cacophony of survival.

Fate’s gentle touch guided Harmonize toward a serendipitous encounter with Diamond Platnumz, a star within Tanzania’s illustrious music scene. The enigmatic energy between them birthed a harmonious union, leading Harmonize to the hallowed halls of Wasafi Classic Baby (WCB), an esteemed record label renowned for its boundless creativity.

In 2015, Harmonize unleashed his soul-stirring debut single, Aiyola, a captivating composition that reverberated in listeners’ hearts. This resounding success became the foundation for a symphony of chart-topping hits, enchanting audiences with the infectious rhythms of Kwa Ngwaru, the magnetic allure of Show Me, and the intoxicating melodies of Kwangwaru.

As the years unfolded, the celestial dance between Harmonize‘s artistic brilliance and the creative prowess of WCB Wasafi blossomed, birthing a mesmerizing tapestry of harmonies and a cascade of triumphant albums. Yet, driven by an indomitable entrepreneurial spirit, Harmonize charted a new course, bidding farewell to familiar shores and venturing into the uncharted territories of his own destiny with the inception of Konde Music Worldwide.

Harmonize‘s creative vision extends beyond the lyrical landscapes he paints beyond music. He has deftly woven his dreams into the fabric of entrepreneurship, manifesting a record label, a stylish clothing line, and even a culinary masterpiece in the form of a restaurant.
