Club Dance music - has various forms, from disco to hip hop. Although there were various interpretations of dance music throughout the history of popular music, Club / Dance became an almost independent genre in the mid-70s of the last century. Just like Soul gave rise to Disco and the appearance of a large number of discos. In the late 70s, Disco style sounded mostly in dance clubs, but by the end of the decade other "young" styles and genres of pop music began to be popular, which ultimately united them in such a direction as Club Dance.
Of course, there were obvious differences between the dance versions of Pop, Hip-Hop, House, Techno and other subgenres, but
what connected them together is definitely an emphasis on rhythm and a simple, catchy melody.
