无伴奏合奏在许多音乐文化中都很常见，但歌手需要很高的技巧来互相聆听并调整音高以保持音调。本研究的目的是从音高准确性（语调）的角度研究四声部（SATB）歌唱中的相互作用。我们特别比较了个别歌手和合作乐团的语调准确性。 20 名参与者（五组，每组四人）在三种不同的聆听条件下演唱了两首音乐：独奏、缺少一个声乐部分和所有声乐部分。经过半自动音高提取和手动校正后，我们对录音进行注释并计算音高误差、旋律音程误差、和声音程误差和音符稳定性。我们观察到个体语调和交互语调之间存在显着差异，更具体地说：1）不使用低音部分唱歌比使用所有声部唱歌具有更小的平均绝对音高误差； 2）当参与者可以听到其他部分时，平均绝对旋律音程误差会增加； 3）单向交互条件下的平均绝对调和区间误差高于双向交互条件下； 4）歌手独唱时发出的音符比与伙伴一起演唱时发出的音符更稳定。
Unaccompanied ensemble singing is common in many musical cultures, yet it requires great skill for singers to listen to each other and adjust their pitch to stay in tune. The aim of this research is to investigate interaction in four-part (SATB) singing from the point of view of pitch accuracy (intonation). In particular we compare intonation accuracy of individual singers and collaborative ensembles. 20 participants (five groups of four) sang two pieces of music in three different listening conditions: solo, with one vocal part missing and with all vocal parts. After semi-automatic pitch extraction and manual correction, we annotated the recordings and calculated the pitch error, melodic interval error, harmonic interval error and note stability. We observed significant differences between individual and interactional intonation, more specifically: 1) Singing without the bass part has less mean absolute pitch error than singing with all vocal parts; 2) Mean absolute melodic interval error increases when participants can hear the other parts; 3) Mean absolute harmonic interval error is higher in the one-way interaction condition than the two-way interaction condition; and 4) Singers produce more stable notes when singing solo than with their partners.
