I have a PIC circuit that will do that (pretty much). It even has a `beat
clock output' already (you get a pulse on every quarter-note). Feed that
into a bit of simple logic (one chip solution: 4017) and you can light
four LEDs easily - one per beat (assuming 4/4)

unless you *really* want to, and think that it's an interesting
engineering exercise..... :)
