We present a hypothesis-driven study on the variation of melody phrases in a collection of Dutch folk songs. We investigate the variation of phrases within the folk songs through a pattern matching method which detects occurrences of these phrases within folk song variants, and ask the question: do the phrases which show less variation have different properties than those which do? We hypothesize that theories on melody recall may predict variation, and as such, investigate phrase length, the position and number of repetitions of a given phrase in the melody in which it occurs, as well as expectancy and motif repetivity. We show that all of these predictors account for the observed variation to a moderate degree, and that, as hypothesized, those phrases vary less which are rather short, contain highly expected melodic material, occur relatively early in the melody, and contain small pitch intervals. A large portion of the variance is left unexplained by the current model, however, which leads us to a discussion of future approaches to study memorability of melodies.
我们展示了一项基于假设驱动的关于荷兰民歌集中旋律短语变化的研究。我们通过一种模式匹配方法来研究民歌中短语的变化，该方法可检测这些短语在民歌变体中的出现情况，并提出问题：变化较少的短语与变化较多的短语是否具有不同的特性？我们假设旋律回忆理论可以预测变化情况，因此，我们研究了短语长度、给定短语在其出现的旋律中的重复位置和次数，以及期待值和主题重复性。我们表明，所有这些预测因素在一定程度上解释了观察到的变化，并且正如所假设的那样，那些较短、包含高度可期待旋律素材、在旋律中出现相对较早且包含较小音程的短语变化较少。然而，当前模型仍有很大一部分方差无法解释，这促使我们讨论未来研究旋律可记忆性的方法。
