The purpose of this study was to investigate the relationship between Portuguese children9s use of singing voice and their singing accuracy on the pitches belonging to the Singing Voice Development Measure (SVDM) criterion patterns (Rutkowski, 2015), as well as the influence on singing with a neutral syllable or text on both variables. Children aged 4 to 9 (n = 137) were administered the SVDM individually and three raters evaluated recordings of the children9s singing, both for the use of singing voice (i.e., effective use of pitch range and register) and singing accuracy. Prior to data analysis, the validity and reliability of the measure was examined and assured. A significant relationship was found between both variables. Favoring the neutral syllable, significant differences were found in response mode for singing accuracy, but not for use of singing voice, suggesting that the use of neutral syllable in classroom singing activities might be beneficial to improve accuracy. Older children and girls obtained higher scores for the use of singing voice and accuracy. Within a common pitch range, children with higher SVDM scores sang accurately a higher number of pitches, suggesting that expanding children9s use of singing voice might also improve singing accuracy.

葡萄牙儿童在用文本和中性音节唱歌时唱歌声的使用与唱歌准确性之间的关系

这项研究的目的是调查葡萄牙儿童9在使用属于唱歌声音发展测度（SVDM）标准模式的音高上的歌声使用率与其歌唱准确性之间的关系（Rutkowski，2015）两个变数的中性音节或文字。分别对4至9岁（n = 137）的儿童进行SVD​​M给药，并且三个评估者评估了儿童唱歌的录音，包括歌声的使用（即有效使用音高范围和调教）以及歌唱的准确性。在进行数据分析之前，要检查并确保该措施的有效性和可靠性。在两个变量之间发现了显着的关系。偏爱中性音节，在回应模式中发现歌唱准确性有明显差异，但不是为了使用唱歌声，这表明在课堂唱歌活动中使用中性音节可能有助于提高准确性。年龄较大的儿童和女孩在唱歌声和准确性方面的得分较高。在相同的音调范围内，具有较高SVDM分数的孩子会准确地唱出更多的音调，这表明扩大孩子对唱歌声的使用也可能会提高唱歌准确性。
