Rest (music) Rest (music) A rest is an interval of silence in a piece of music, marked by a symbol indicating the length of the pause. Each rest symbol and name corresponds with a particular note value for length, indicating how long the silence should last. Rests are intervals of silence in pieces of music, marked by symbols indicating the length of the pause. Each rest symbol and name corresponds with a particular note value, indicating how long the silence should last, generally as a multiplier of a measure or whole note. When an entire bar is devoid of notes, a whole
Time value of money not already occurred), or simply not define the value at that point. In case the discount rate is constant, formula_47 this simplifies to where formula_49 is "time remaining until cash flow". Thus for a stream of cash flows "f"("u") ending by time "T" (which can be set to formula_50 for no time horizon) the value at time "t," formula_51 is given by combining the values of these individual cash flows: This formalizes time value of money to future values of cash flows with varying discount rates, and is the basis of many formulas in financial mathematics, such as the Black–Scholes
