Harmonize: Full Biography from Humble Beginnings to Music Stardom
Early Life and Background
Harmonize, whose real name is Rajab Abdul Kahali, was born on March 15, 1991, in Mtwara, a region located in southern Tanzania. He grew up in a modest family, experiencing the everyday struggles of a typical Tanzanian household with limited financial resources. Despite these challenges, Harmonize demonstrated a strong sense of determination and ambition from an early age. His upbringing in Mtwara, far from the vibrant music industry of Dar es Salaam, played a significant role in shaping his personality and the grounded nature that many fans love about him today.
After completing his secondary education in 2009, Harmonize made a bold decision to move to Dar es Salaam, the commercial capital of Tanzania. The move was fueled by his dream to become a professional musician. However, life in the city was far from easy. To survive, he worked a variety of informal jobs, including selling water in the streets and hawking clothes in the busy markets of Kariakoo. Despite his harsh living conditions, he never lost sight of his goal to one day make it big in the music industry.
Early Attempts in Music
Harmonize's journey into music was filled with perseverance. He began writing songs and recording demos, despite having little access to quality studios or financial support. In 2011, he participated in the Bongo Star Search talent competition, hoping to gain exposure and advance his music career. Although he was eliminated early in the competition, the experience gave him valuable insights into the industry and only fueled his desire to succeed.
Over the next few years, he continued networking within the music scene in Dar es Salaam. It was during this time that he caught the attention of Diamond Platnumz, one of Tanzania’s biggest music stars and the founder of WCB Wasafi, a record label that would later become a major turning point in Harmonize’s career.
Breakthrough with WCB Wasafi
In 2015, after years of hustle and rejection, Harmonize’s career finally took a huge leap forward when he was signed to WCB Wasafi. Diamond Platnumz recognized his potential and took him under his wing. That same year, Harmonize released his debut single “Aiyola,” which became a massive hit across East Africa. The song marked the beginning of his rise to stardom, as it gained millions of views and streams, catapulting him into the limelight.
Under WCB Wasafi, Harmonize enjoyed immense success. He followed up with more chart-topping songs like “Bado” featuring Diamond Platnumz, “Show Me” featuring Rich Mavoko, and the mega-hit “Kwa Ngwaru,” also featuring Diamond Platnumz. These tracks not only solidified his place in the Tanzanian music industry but also introduced him to audiences across Africa and the diaspora.
Departure from WCB and the Birth of Konde Music Worldwide
In 2019, after four successful years with WCB Wasafi, Harmonize made the decision to leave the label and pursue an independent career. The move was seen as controversial, but he later explained that he wanted more creative control over his music and the freedom to grow as a business-minded artist. To make this transition, he had to pay a reported exit fee to the label, which showed his commitment to his future.
Shortly after his departure, he launched his own record label, Konde Music Worldwide, named after his popular nickname “Konde Boy.” The label aimed to empower other talented artists and provide them with the platform that he never had when he started out. Some of the artists who have been signed under Konde Music include Ibraah, Killy, Cheed, and Anjella.
