Harsh sounds can make well-known chords sound fresh. More than 450 years ago, at the end of the renaissance, the most famous theoretician of the age, Zarlino said that dissonance itself is not enjoyable to hear but increases the impact of consonance coming after it. We perceive it like light after darkness or sweet after bitter. The longer dissonance lasts, the sweeter the release will be. For some people, contemporary music means a monopoly of dissonance. For them it's easy to see how rewarding it is to play contemporary music together with classical music: Purcell, Bach, and Mozart will sound even more glorious and sweet. Classic Lights I. shows that sometimes the questions posed by modern music can be answered by classical pieces from the past.
