Henk Badings (January 17, 1907 – June 26, 1987) was an Indonesian-Dutch composer known for his pioneering work in electronic music and the use of unconventional musical scales. Born in Bandung, Java, in the Dutch East Indies, Badings was orphaned at a young age and moved to the Netherlands in 1915. Despite his guardians' wishes for him to pursue a career in geology, Badings gravitated towards music, initially teaching himself before studying composition with Willem Pijper.

Badings achieved early success with his First Cello Concerto performed at the Concertgebouw in Amsterdam in 1930. He held teaching positions at various institutions, including the Rotterdam Conservatory and the Musikhochschule Stuttgart. During World War II, he faced accusations of collaboration with Nazi forces but was reinstated in the music community by 1947.

In the 1950s, Badings gained international recognition for his electronic compositions and innovative use of tape recording. He founded the electronic music studio at Philips in Eindhoven and contributed significantly to the development of 31-tone music. His compositions include fifteen symphonies, numerous concertos, and various other orchestral and chamber works. Badings' music often employed the octatonic scale and the harmonic series scale, which he termed 'lydo-mixolydian.'

Throughout his career, Badings received numerous commissions and accolades, contributing significantly to 20th-century Dutch music. His work remains influential, with renewed interest in his compositions in the 21st century.
