Information about Pedal

''Distinguish from paddle and petal and the verb peddle.


The word pedal comes from the Latin (Pes, Pedis) and relates to the foot.

A pedal is a lever activated by one's foot. Examples include:
  • An automobile has usually three pedals. See automobile pedal.
  • Bicycle pedal: on a bicycle, each of two platforms at the end of the crankarms, connected such that while the crank arms rotate, the pedals can stay parallel to the shoe soles; this human powered rotation provides the propulsion, usually through a bicycle chain that makes the back wheel turn. In the case of a back pedalling brake, they are also used for applying the brake in the back wheel, again through the chain.

  • Tap pedal: this is a small electronic pedal, similar or identical to the ones used with synthesizers, but is connected to audio effects equipment, a music sequencer, or drum machine.

When connected to audio effects, it can be used to "tap in" the length for a digital delay or flange, or to cause an effect loop to be bypassed.
  • Pedal tone: a nonchord tone, usually the tonic or dominant held for an extended period of time.
  • Pedal pumping is the sexual fetish of seeing women use pedals, usually in cars.
