Abstract
The tempo of music performance is often accelerated irrespective of players’ intention. Though the characteristics of the tempo deviation phenomenon have been investigated using a finger-tapping task, most such studies dealt with tapping with a fixed interval and intensity; few studies considered the effects of rhythm and accent, both important factors of music performance. Here, we asked how different rhythm and accent patterns affected the tempo-keeping property using a synchronization-continuation task paradigm: Participants were asked to keep tapping while reproducing the given rhythm/accent patterns designated by the target tones. Tapping tempo was significantly deviated depending on rhythm/accent patterns, but their magnitudes were only several percent in 150 seconds, much smaller than those in real music performance. We also ran experiments under the conditions that participants need not reproduce the accent patterns but only response tones were accented. These auditory modulations affected the tempo deviation, implying that perceptual processes induced by the auditory feedback also influence the tempo maintenance. Inter-tap intervals (ITIs) were modulated by the accent pattern, but no clear relationship was observed between ITI fluctuations and long-term tempo deviation, suggesting that different mechanisms are involved. In sum, the present finding shows that non-uniform motor actions required for music articulation can disturb the long-term tempo maintenance but their effect is rather small. We also reported the tempo deviation when the response tone was modulated by loudness (crescendo vs. diminuendo) or pitch (ascending vs. descending).

Description of the data and file structure
Raw bar length data
Files named "barlength_raw_expXY.csv" give the bar length data (unit: second) in three experiments of this study, where X means the experiment number and Y means the experimental condition (For example, exp1A means the condition A in Experiment 1). As for Experiment 3, A, B, ... and E mean Control, Crescendo, Diminuendo, Ascending and Descending, respectively.
- 1st column: participant ID
- 2nd column: trial number for each participant
- 3rd to end columns: length of each bar
- 1st row: index of the bar (a negative number means the synchronization phase, and 0 or a positive number means the continuation phase)
"NaN" means missing data in these files. In Experiment 3, bar length was determined as the half of the sequence length because a bar consisted of 4 beats while a tone sequence consists of 8 tones.
Slope and intercept data
Files named "slope_expX.csv" and "intercept_expX.csv" give the slopes and intercepts obtained by the regression analysis of bar length data of each trial, which are used to draw Figures 3, 4, 5 and 8.
- 1st column: participant ID
- 2nd column: trial number for each participant
- 3rd to end columns: estimated slope (or intercept)
- 1st row: experimental condition
Relative Slope data
Files named "relativeslope_expX.csv" give the relative slopes to the control condition for each participant (i.e., the difference in slope between a specific condition and the control condition). These data are used to draw Figures 4, 5 and 8.
- 1st column: participant ID
- 2nd to end columns: relative slope
- 1st row: experimental condition
Summarized tapping strength data
Files named "force_ratio_expX.csv" are the average tapping force ratio to the first beat in the continuation phase, which was used to draw Figure 6.
- 1st column: participant ID
- 2nd column: trial number for each participant
- 3rd to end columns: median force ratio to that of the first beat
- 1st row: experimental condition and tap position (For example, A_1 means the first tap of condition A).
Summarized inter-tap-interval (ITI) data
Files named "ITI_expX.csv" summarizes the median ratios of inter-tap-intervals (ITIs) to the bar length, which was used to draw Figure 7.
- 1st column: participant ID
- 2nd column: trial number for each participant
- 3rd to end columns: median force ratio to that of the first beat
- 1st row: experimental condition and tap position (For example, A_1 means the first tap of condition A).
