Singing just-tuned chords predicts rapid pitch drift flat

Evidence

FIGURE 4.43 Predicted Pitch Drift Based on Just Tuning for the Exercise Shown in Figure 4.42. The 13 chords of the exercise are predicted for each part separately and therefore indicated as “note number” on the x-axis (adapted from Howard, 2007a). — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1384

Categorization

• DEFINE: Distinguishes predicted drift under just tuning as a theoretical model to be compared with measurement.
• XREF: Connects to the chapter’s treatment of tuning systems and temperament as perceptual rather than merely mathematical choices.
• corroborated: 2 independent passages support this claim — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1384
