How does a metronome work?

Question

I don't really get it..... is there added energy... or... what does it run on...

And I mean the original metronome, that sway back and forth....

Answer 1

The original type of metronome, to which you refer, is basically a clock mechanism.

The energy is stored in the spring when it is wound and is released at a rate governed by the escapement.

The escapement uses a pendelum, which is the part which you see swinging back and forth.

The rate of a pendelum depends on its length.

The length is effectively altered by sliding the weight to different positions on the pendelum which changes the distance of its centre of gravity from the fulcrum (pivot).

Answer 3

"One common type of metronome is the wind-up metronome, which uses a weight on the end of a rod to control the tempo (slide the weight up the rod to decrease tempo, or down the rod to increase tempo). The pendulum rod swings back and forth in tempo; mechanics inside the metronome produce a clicking sound on each swing of the rod...

...For example, if the user selects four beats per measure (for example a time signature of 4/4), then the metronome might sound like so:
Ching!, tick, tick, tick,
Ching!, tick, tick, tick, …
while an irregular meter of 7/8 might produce this pattern:
Ching!, tick, tock, tick, tock, tick, tick,
Ching!, tick, tock, tick, tock, tick, tick, ..."

Answer 4

I'm sure they use similar parts to a watch and a metronome to help it keep good timing.

Answer 5

Earth's gravity keeps the metronome in motion.

Answer 6

it is a crank machine that has a weight on the end to keep it moving and the tick sounds it makes is how many beats per minute.
