A traditional clock face is a ruler(rule) divided into 12 equal spatial distances, it does not measure time, or space but velocity, it is a speedometer measuring the speed which the hour hand completes a circuit relative to the time it takes the earth to revolve in space.
24 hours a day = 24 units of space on the clock face divided by the time it takes the earth to complete 1 revolution, a clock is a speedometer this logic lead Einstein to formulate his special theory of relativity where measurements of space and time are linked as different ways of describing the same phenomena.
A metronome is another kind of speedometer, it measures space÷time .

Sorry, I don't know what you’re talking about or what any of that has to do with the guitar.
