Two hundred fifty-sixth note the whole note even smaller. Two hundred fifty-sixth note In music, a two hundred fifty-sixth note (or occasionally demisemihemidemisemiquaver) is a note played for of the duration of a whole note. It lasts half as long as a hundred twenty-eighth note and takes up one quarter of the length of a sixty-fourth note. In musical notation it has a total of six flags or beams. Since human pitch perception begins at 20 Hz (1200/minute), then a 256th-note tremolo becomes a single pitch in perception at quarter note ≈ 80 bpm. A single 256th note is always stemmed with flags, while
Time value of money is to emphasize that "u" is a "parameter" (fixed in any instance—the time when the cash flow will occur), while "t" is a "variable" (time). In other words, future cash flows are exponentially discounted (exp) by the sum (integral, formula_44) of the future discount rates (formula_45 for future, "r"("v") for discount rates), while past cash flows are worth 0 (formula_46), because they have already occurred. Note that the value "at" the moment of a cash flow is not well-defined – there is a discontinuity at that point, and one can use a convention (assume cash flows have already occurred, or
