Four on the floor (music) in the context of "Techno music"

A sentimental ballad is an emotional style of music that often deals with romantic and intimate relationships, and to a lesser extent, loneliness, death, war, drug abuse, politics and religion, usually in a poignant but solemn manner. Ballads are generally melodic enough to capture the listener's attention.

Sentimental ballads are found in most music genres, such as pop, R&B, soul, country, folk, rock and electronic music. Usually slow in tempo, ballads tend to have a lush musical arrangement which emphasizes the song's melody and harmonies. Characteristically, ballads use acoustic instruments such as guitars, pianos, saxophones, and sometimes an orchestral set. Many modern mainstream ballads tend to feature synthesizers, drum machines and even, to some extent, a dance rhythm.

House music, or simply house, is a genre of electronic dance music characterized by a repetitive four-on-the-floor beat and a typical tempo of 115–130 beats per minute. It was created by DJs and music producers from Chicago's underground club culture and evolved slowly in the early/mid 1980s as DJs began altering disco songs to give them a more mechanical beat. By early 1988, house became mainstream and supplanted the typical '80s music beat.

House was created and pioneered by DJs and producers in Chicago such as Frankie Knuckles, Ron Hardy, Jesse Saunders, Chip E., Joe Smooth, Steve "Silk" Hurley, Farley "Jackmaster" Funk, Marshall Jefferson, Phuture, and others. House music initially expanded to New York City, then internationally to cities such as London, and ultimately became a worldwide phenomenon.

Techno is a genre of electronic dance music (EDM) which is generally produced for use in a continuous DJ set, with tempos being in the range from 120 to 150 beats per minute (bpm). The central rhythm is typically in common time (
₄) and often characterized by a repetitive four on the floor beat. Artists may use electronic instruments such as drum machines, sequencers, and synthesizers, as well as digital audio workstations. Drum machines from the 1980s such as Roland's Roland TR-808 and Roland TR-909 are highly prized, and software emulations of such retro instruments are popular in this style.

Much of the instrumentation in techno is used to emphasize the role of rhythm over other musical aspects. Vocals and melodies are uncommon. The use of sound synthesis in developing distinctive timbres tends to feature more prominently. Typical harmonic practices found in other forms of music are often ignored in favor of repetitive sequences of notes. More generally the creation of techno is heavily dependent on music production technology.
