Abstract The score of Luciano Berio’s Sequenza VII for solo oboe exhibits a strict and definite temporal space, yet most performers do not manage to perform the work within the prescribed time. The score is presented as a matrix with thirteen lines and columns and each line undergoes a temporal compression. The impetus of this practitioner-based study was driven by a need to find a method of performing the unusual time increments and to be as close as possible to the composer’s intent regarding the temporal grid. The aim of this study was to investigate and demonstrate a method of calculating and performing the intended duration of Sequenza VII so that the performance realises the absolute duration intended by Berio. Two methods were used to calculate the total duration of the composition. The result of the precise calculation of the predetermined total duration of Sequenza VII is six minutes and thirty seconds, and therefore refines the results of previous explorations of this subject by other scholars.

精确计算卢西亚诺·贝里奥（Luciano Berio）对双簧管演奏的Sequenza VII的总预期时长

摘要卢西亚诺·贝里奥（Luciano Berio）的Sequenza VII的单簧管乐谱具有严格而明确的时间空间，但大多数表演者未能在规定的时间内完成工作。分数显示为具有十三行和一列的矩阵，并且每行经历时间压缩。这项基于实践者的研究的推动力是需要找到一种执行异常时间增量并尽可能接近作曲家关于时间网格的意图的方法。这项研究的目的是调查和演示一种计算和执行Sequenza VII预期持续时间的方法，以便该性能实现Berio预期的绝对持续时间。使用两种方法来计算组合物的总持续时间。
