This article discusses the use of complex rhythmic structures, such as tuplets within triplets in piece Percussion Study II, of 1993, by the Brazilian composer Arthur Kampela. In some cases, it will be shown notational procedures of complex writing by British composer Brian Ferneyhoug. By turning a quarter note in one of five tuplet, Ferneyhough uses an above the tuplet symbology, indicating that there are five sixteenth notes instead of four sixteenths; the British composer thus uses an indication of the same rhythmic figure, using the sixteenth note. In Percussion Study II, Arthur Kampela uses a peculiar writing in which he does the same indication of rhythmic figures such as Brian Ferneyhough. This article proposes a discussion about this peculiar writing in Percussion Study II and finally there will be shown the complex script from the standpoint of other composers such as Pierre Boulez, and from this vision, will be offered other possibilities notational Percussion in Study II.
