“…Nearly all regressions significantly confirm the predictions of Kats and Smelik who suggested that Ionian, Aeolian, and Mixolydian modes would be relatively popular because these modes sound familiar to ears used to major and minor scales, and indeed there is a connection between familiarity, processing fluency, and liking (Huron, 2013; van Balen, 2016). Nevertheless, it is not certain whether the preference for these modes is really based on familiarity, as it is visible as early as 1606 (Marti, 2004; when the change in tonal system was far from complete) and furthermore, even in our times the diatonic modes have been used quite regularly in folk and rock music (Moore, 1992; Powers, Porter, & Cowdery, 2001; Temperley & de Clerq, 2013). As the Ionian mode is perceived as happy (Temperley & Tan, 2013), an alternative explanation for its popularity would be that Calvinist protestants prefer happy music.…”
