Lyrically, "Ring The Alarm" features Knowles impersonating a threatened girlfriend and shows her unwillingness to let another woman to profit from all the work she did to improve her love interest's life. Critical reception of the song was generally mixed to positive with several music critics noting that the song was different from Knowles's previous work. While some complimented the distorted, angry and assertive vocals of Knowles' others showed disappointment with the lyrical arrangement.
