The TK Band has its roots in the school bands of former Tanjong Katong Technical School (now Tanjong Katong Secondary School) and Tanjong Katong Girls' School. The bands started separately in 1965 with only 26 members. In 1967, the two bands came together for a combined performance that marked their long relationship. The band split again in 1989, with TKGS going its own way. Since established, it has represented the republic in several overseas events and International Bands' festivals. In 1998, the band was invited to put up a solo performance in the National Day Parade (NDP), the first ever for any school band. It also appeared on National Day Parades 2002, 2004 (during the pre-parade segments in both years), NDP 2012, Chingay Parades, etc., in solo performances. In 2014, TK Band was invited to play at the Taoyuan Band Festival in Taiwan (Republic of China). TK Band was also invited to play at the Singapore Youth Festival Opening Ceremony 2014 held at Gardens by the Bay.
