- In Part 1, we examined a single example, C5, and examined the differences from intentionally spreading the unisons by 0.5¢, and comparing them to a tighter tuning with virtually no spread.
- You may go back and review that video if you have not seen it, found on YouTube at the following URL

- In this Part 2, we examine the behavior of the C's, from C2–C7:
- Partial Drift in Frequency
- Partial Drifts in Amplitude
- Corresponding to the same window lengths and time samples set by the spectrogram parameters.
- In each case starting with the best no-spread tuning available to us.
- In each case, as before, we show the results from full unison coupled strings.
- The individual strings have a much simpler decay characteristic.
- The challenge to the piano tuner is to get the final result from the full couplings.
- Illustrating the significance of the Weinrich Drift and the sometimes-extreme divergence of the partials, especially the fundamental as we will see.
- All examples taken from my Fazioli F308, regulated to full factory specifications.
