The Time Frequency (TTF) are a Scottish electronic dance music group, founded by Jon Campbell in early 1990.

[1] Members that TTF have included are fellow keyboard players Paul Inglis, Steven Nelson, Kyle Ramsay and later Colin McNeil.

Mary Kiani was the lead singer of TTF, followed by Jo Wilson, Debbie Millar and Lorena Dale.

[citation needed] During this period, an album titled Escape was completed and planned to be released on Virgin Records, although this fell through due to disagreements with the label.

[6] In 2018, the Time Frequency released two non-album singles, "Home" and "In Heaven", with the latter featuring posthumous vocals by Millar.
