Double whole note Double whole note In music, a double whole note (American), breve (international), or double note (; ) is a note lasting two times as long as a whole note (or "semibreve"). It is the second-longest note value still in use in modern music notation (; ). In medieval mensural notation, the "brevis" was one of the shortest note lengths in use —hence its name, which is the Latin etymon of "brief". In "perfect" rhythmic mode, the brevis was a third of a "longa", or in "imperfect" mode, half a "longa" . In modern notation, a breve is commonly represented in
Time value of money at future time "n": Summing over all payments from time 1 to time n, then reversing t Note that this is a geometric series, with the initial value being "a" = "C", the multiplicative factor being 1 + "i", with "n" terms. Applying the formula for geometric series, we get The present value of the annuity (PVA) is obtained by simply dividing by formula_19: Another simple and intuitive way to derive the future value of an annuity is to consider an endowment, whose interest is paid as the annuity, and whose principal remains constant. The principal of this hypothetical endowment
