Metric modulation: 2 half notes = 3 half notes or Play with eighth note subdivision for tempo/metre comparison Thus if the two half notes in 4 4 time at a tempo of quarter note = 84 are made equivalent with three half notes at a new tempo, that tempo will be:

The Intel 8253 PIT was the original timing device used on IBM PC compatibles.It used a 1.193182 MHz clock signal (one third of the color burst frequency used by NTSC, one twelfth of the system clock crystal oscillator, [1] therefore one quarter of the 4.77 MHz CPU clock) and contains three timers.
A countdown is a carefully devised set of procedures ending with launch of a rocket. Depending on the type of vehicle used, countdowns can start from 72 to 96 hours before launch time. There are two countdowns proceeding simultaneously:
An hourglass (or sandglass, sand timer, or sand clock) is a device used to measure the passage of time. It comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (historically sand) from the upper bulb to the lower one due to gravity. Typically, the upper and lower bulbs are symmetric so that ...
Set the Pomodoro timer (typically for 25 minutes). [1] Work on the task. End work when the timer rings and take a short break (typically 5–10 minutes). [5] Go back to Step 2 and repeat until you complete four pomodori. After four pomodori are done, take a long break (typically 20 to 30 minutes) instead of a short break.
