Hello all, What exactly is meant by a linear or exponential tempo change ? Is the tempo a lin/exp function of time, or of score position ?
A bit of algebra leads to this: Let t = time (seconds) p = score position (beats) v = tempo (beats / second) [1] We have v = dp / dt # by definition If v is a linear function of t, then v (p) = square root of a linear fuction of p If v is a exponential function of t, then v (p) = a linear function of p if v is a linear function of p then v (t) = an exponential function of t If v is an exponential function of p, then v (t) = inverse of a linear function of t So there is plenty of room for confusion...
