Frap an anglicized version of the French ‘frapper’ meaning ‘to hit’ was commissioned by the Safri Duo of Danish electronic Percussionists as a short opener for their concerts. Wallin describes thelighthearted pieces as ‘a game exploring togetherness and not-togetherness’. At various points the musicians are instructed to play in unison in syncopation or freely or to play in canon with an eighth (quaver) note separationand are given other choices. Therefore each performance of Frap will be unique. Composer Rolf Wallin is a renowned Nordic composer whose work encompasses elements of classical training jazz early music and avant garde rock while incorporating a wide range of techniques and expressions.
