Half-time (music) each measure (a whole note) is divided in two by the bass drum (half note), each half is divided in two by the snare drum (quarter note, collectively the bass and snare divide the measure into four), and each quarter note is divided in two by a ride pattern (eighth note). "Half"-time refers to halving this division (divide each measure into quarter notes with the ride pattern), while "double"-time refers to doubling this division (divide each measure into sixteenth notes with the ride pattern). A classic example is the half-time shuffle, a variation of a shuffle rhythm, which is used
Time value of money the contributions of "FV", the value of cash flow at time "t": Note that this series can be summed for a given value of "n", or when "n" is ∞. This is a very general formula, which leads to several important special cases given below. In this case the cash flow values remain the same throughout the "n" periods. The present value of an annuity (PVA) formula has four variables, each of which can be solved for by numerical methods: To get the PV of an annuity due, multiply the above equation by (1 + "i"). In this case each
