Common musical aesthetics include a bass-heavy drumbeat, often emulating the slowed down breakbeat samples typical of hip hop in the 1990s, giving the genre a more psychedelic touch. Vocals in trip hop are often female and feature characteristics of various singing styles including
jazz and rock. The female-dominant vocals of trip hop may be partially attributable to the influence of genres such as jazz and early R&B, in which female vocalists were more common. However, there are notable exceptions -

Rhodes pianos, saxophones, trumpets, and
flutes, and may employ unconventional instruments such as the
Mellotron. Trip hop differs from hip hop in theme and overall tone. Instead of

hardcore rap styles and lyrics with atmospheric overtones to create a more mellow tempo.
