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 two or more are usually
Value of time can be examined. For example, if a traveler has a choice between a coach which takes six hours and costs £10, or a train which takes four hours and costs £30, we can deduce that if the traveler chooses the train, their value of time is £10 per hour or more (because they are willing to spend "at least" £20 to save two hours' travel time). The difficulty in narrowing down the "actual" value of time from a pair of choices means that hypothetical situations are generally used (the stated preference technique) to deduce values of time. The value of
