How to use this workflow
Mark musical landmarks
Choose repeated beat onsets or score locations. Do not infer a beat from every ornamental note.
Separate the segments
Record the number of intervals and elapsed seconds for each segment, with a note about the beat unit.
Keep local and overall figures
Calculate each local BPM and the overall interval count divided by total time. Do not average BPM numbers blindly.
Three four-interval segments with unequal durations
Consider an invented phrase with four intervals in 2.0 s, four in 2.4 s and four in 1.8 s. The local averages are 120, 100 and 133.333 BPM. Twelve total intervals over 6.2 s give 116.129 BPM overall.
The plain arithmetic mean of those three BPM values is 117.778 BPM, which does not reproduce the total duration. This authored worksheet shows why retaining elapsed times is more useful than reporting an unexplained average. It is not a measurement of a historical performance.
Swipe or scroll sideways to read all columns.
| Segment | Intervals | Time | Local average |
|---|---|---|---|
| Opening | 4 | 2.0 s | 120 BPM |
| Expansion | 4 | 2.4 s | 100 BPM |
| Arrival | 4 | 1.8 s | 133.333 BPM |
Choose a practice goal before imposing a click
Tap BPM can record your local pulse estimate but does not export a tempo map. Reset between windows and record timestamps outside the tool. A single changing tap sequence will blend recent timings rather than explain the phrasing.
For coordination practice, you may deliberately replace the phrase with a steady click. For interpretation study, keep the original timing and compare the same landmarks. Neither choice proves that the performer was inaccurate; the goal determines the useful reference.
