Two metronomes are placed on a common base. The metronome on the left is set at 192 beats per minute. The one on the right is set at a slightly lower rate. The metronome pendulums are initially out-of-phase. The two pendulums oscilate in phase due to conservation of momentum and coupling via the base. A true physics masterpiece!

Suppose they were on the floor. They would go into phase, out, and in again. They would not lock.
Coupled by a movable base, they transfer enough energy to one another to overcome the pre-set mechanical frequency.
Compare this to adjacent strings on a piano. Do they pull each other into pitch? Do wind instruments pull each other into pitch?
If digital oscillators can be made sensitive to pitches already playing, can one get the same tightness on a tempered keyboard that a garage band gets?
so basically the wooden base is what's converted the change in momentum, you'll have to forgive me it's been while since school what is the equation for that
It's not a problem with the metronomes, it's just the way the world works. They start anti-phase, and end up in-phase. There are no other stable alternatives so 2 pendulums set closely together, with similar BPMs will always end in-phase. It works with people too... creepy isn't it?
