I wanna make a Minecraft noteblock song, and don't know how long a beat is in seconds (4/4). I know that 10 redstone ticks are in one second. I can use repeaters as rests, but I need to set the delay of the repeaters, and I can't make rests if I don't know how long a beat is, so please help me.
Edit: By the way everytime you right-click a repeater, the delay increases by 1 redstone tick. The delay is set to 1 redstone tick (or 0.1 seconds) by default. If you right click it after the delay reaches four redstone ticks, it goes back to one redstone tick.
