metronome

MEH-troe-nome
[English, ]
A mechanical or electronic device that keeps a regular beat (or pulse) and may be adjusted to any desired speed (tempo), used by musicians for practicing difficult rhythmic passages

The metronome was invented and patented by the German inventor, Johann Nepomuk Mälzel (August 15, 1772 - July 21, 1838) in 1816, on the suggestion of composer Ludwig van Beethoven. The marking M.M. at the beginning of a composition originally stood for "Mälzel Metronome," but has since come to designate "Metronome Marking." 

This marking identifies the tempo of the composition in terms of the number of beats per minute. Thus, if the M.M. shows the quarter note to equal 60, that means the tempo should be 60 beats per minute or one beat per second.
