In tone languages, alteration of lexical tone changes the intended meaning. This implies that composers should equally match lexical tone in their music for intelligible communication of the intended textual messages, a compositional approach termed Lexical Tone Determinants (LTD) in this study. Yet, in the Ìgbò language setting, some composers creatively disregard/mismatch lexical tone, which is branded as Musical/Creative Determinants (M/CD). It is believed that mismatched lexical tone in Ìgbò music alters listeners’ comprehension of the intended messages; on the other hand, it is argued that thorough match of lexical tone constrains musical creativity. Listeners’ perception of textual messages in LTD and M/CD music has not been empirically tested (side-by-side) to verify whether comprehension is lost or not, at least, in the Ìgbò language context. This empirical void gap is verified in this particular study to substantiate the propositions/findings using comparative measures to collect data through listeners’ perception in live-performance of newly composed LTD and M/CD pieces. Specifically, it examines whether mismatched lexical tone in Ìgbò music alters message comprehension or not. The data were collated, presented, and analyzed statistically with chi-square deployed to evaluate their difference in message comprehension.

可以理解伊博音乐中不匹配的词汇音调的预期信息吗？听者对匹配和不匹配作品的感知测试

在声调语言中，词汇声调的改变会改变预期的含义。这意味着作曲家应该在他们的音乐中同样匹配词汇音调，以便对预期的文本信息进行可理解的交流，本研究中称为词汇音调决定因素 (LTD) 的作曲方法。然而，在 Ìgbò 语言环境中，一些作曲家创造性地忽略/不匹配词汇音调，这被称为音乐/创意决定因素 (M/CD)。人们认为 Ìgbò 音乐中不匹配的词汇音调会改变听众对预期信息的理解；另一方面，有人认为词汇声调的彻底匹配会限制音乐的创造力。听众对 LTD 和 M/CD 音乐中文本信息的感知尚未经过经验测试（并排），以验证理解是否丢失，至少，在 Ìgbò 语言环境中。这一经验空白差距在本特定研究中得到验证，以通过听众在新创作的 LTD 和 M/CD 作品的现场表演中的感知收集数据，使用比较措施来证实命题/发现。具体来说，它检查了 Ìgbò 音乐中不匹配的词汇音调是否会改变信息理解。使用卡方对数据进行整理、呈现和统计分析，以评估它们在消息理解方面的差异。它检查 Ìgbò 音乐中不匹配的词汇音调是否会改变信息理解。使用卡方对数据进行整理、呈现和统计分析，以评估它们在消息理解方面的差异。它检查 Ìgbò 音乐中不匹配的词汇音调是否会改变信息理解。使用卡方对数据进行整理、呈现和统计分析，以评估它们在消息理解方面的差异。
