Previous studies have revealed uneven duration patterns at the sixteenth note level of samba. In the present study, we investigated the influence of tempo on such sixteenth-note patterns in a performed samba groove.The results revealed an uneven duration pattern in all tempi. Interestingly, the shortest note becomes relatively shorter and the longest relatively longer as the tempo increases. We suggest that the differences in relative durations between tempi reflect the need to maintain the samba sixteenth note ‘template’ in all tempi: producing the samba ‘feel’ requires that relative durations have to be adjusted to tempo.

节奏对演奏的桑巴律动中相对音符持续时间的影响

先前的研究已经揭示了桑巴十六分音符级别的不均匀持续时间模式。在本研究中，我们研究了速度对演奏的桑巴律动中这种十六分音符模式的影响。结果显示所有速度中的持续时间模式不均匀。有趣的是，随着速度的增加，最短的音符变得相对较短，最长的音符变得相对较长。我们建议，速度之间相对持续时间的差异反映了在所有速度中保持桑巴十六分音符“模板”的需要：产生桑巴“感觉”要求必须将相对持续时间调整为速度。
