Short answers, pulled from the story.
Ghetto house, also called booty house, is a subgenre of house music that began being recognized as a distinct style from around 1992 onwards. It features minimal Roland 808 and 909 drum machine-driven tracks and sometimes sexually explicit lyrics.
Ghetto house relies primarily on Roland 808 and 909 drum machines for its synthesized tom-tom sounds, clap sounds, and kick drum patterns. Producers typically use minimal analogue synths and little or no effects alongside these machines.
Key ghetto house artists include DJ Deeon, Jammin' Gerald, DJ Funk, DJ Milton, DJ Slugo, Waxmaster, Traxman, and Parris Mitchell.
"It's Time for the Percolator" by Cajmere is identified as the primary template of classic Chicago house music that ghetto house producers built upon, adding sexually explicit lyrics to that structural foundation.
Juke music, also known as juke house or Chicago juke, is a faster subgenre that emerged from ghetto house in the late 1990s. Juke songs run at roughly 150-165 BPM and were created to match the energy of footwork, a dance style born in the ghettos, house parties, and underground dance competitions of Chicago.
RP Boo, a former footwork dancer, is generally credited with making the first songs that fall within the juke canon.
