Hundred twenty-eighth note Hundred twenty-eighth note In music, a hundred twenty-eighth note or semihemidemisemiquaver or quasihemidemisemiquaver is a note played for of the duration of a whole note. It lasts half as long as a sixty-fourth note. It has a total of five flags or beams. Since human pitch perception begins at 20 Hz (1200/minute), then a 128th-note tremolo becomes a single pitch in perception at quarter note ≈ 160 bpm. A single 128th note is always stemmed with flags, while two or more are usually beamed in groups. Notes this short are very rare in printed music, but not unknown. One reason
Time value of money multiply the PV of an ordinary annuity by (1 + "i"). The following formula use these common variables: The future value ("FV") formula is similar and uses the same variables. The present value formula is the core formula for the time value of money; each of the other formulae is derived from this formula. For example, the annuity formula is the sum of a series of present value calculations. The present value ("PV") formula has four variables, each of which can be solved for by numerical methods: The cumulative present value of future cash flows can be calculated by summing
