Kaps Freed

Music composition for piano and electronics.Composed 2017.You can use the MaxPatch provided (created by Stuart James) or create your own software to realise the score. You need the Decibel ScorePlayer and the associated score file to perform this work. Commissioned by Gabriella Smart. PROGRAM NOTEThis composition aims to bring the sound of the piano as close as possible to the sound of Percy Grainger’s Free Music ideals, by applying pitch tracking and spectral filtering. Delicate, sparse piano pitches are sampled and transported into theremin like tones where the tempered scale becomes irrelevant. The 'Kaps piano' is the childhood piano of Percy Grainger, and resides in the Grainger Museum in Melbourne. It was made in Dresden, Germany in 1887. Grainger practiced on this piano daily as a child, presided over by his teacher and mother, Rose Grainger. Hope has long been fascinated with Grainger's Free Music, having realised performances of the theremin works. Kaps Freed imagines a link between his childhood piano practice routine and his later investigations into Free Music - a music characterised by the emancipation of rhythmic processes and pitch, both explored in this, and most of Hope's work. The piano notation is inspired by Albert Lake in Melbourne, the same lake that is said to have been the inspiration for Grainger's theory of Free Music.

本作品为钢琴与电子音乐结合的创作，完成于2017年。您可使用斯图尔特·詹姆斯（Stuart James）制作的预设MaxPatch，或自行编写软件以实现乐谱的演奏呈现。演绎本作品需使用Decibel ScorePlayer及其配套乐谱文件。本作品由加布里埃拉·斯马特（Gabriella Smart）委托创作。

【作品解说】本作品通过音高追踪与频谱滤波技术，力求让钢琴音色尽可能贴近珀西·格兰杰（Percy Grainger）的自由音乐（Free Music）理念。细腻稀疏的钢琴音高被采样并转换为类似特雷门琴（theremin）的音色，此时十二平均律将不再适用。“卡普斯钢琴（Kaps piano）”为珀西·格兰杰童年所用的钢琴，现收藏于墨尔本格兰杰博物馆。该钢琴于1887年在德国德累斯顿制造，格兰杰童年时期在其教师兼母亲罗丝·格兰杰（Rose Grainger）的陪同下，每日使用此琴练习。作曲家霍普（Hope）长期痴迷于格兰杰的自由音乐理念，此前曾完成特雷门琴作品的演奏。《Kaps Freed》旨在构建其童年钢琴练习日常与后续自由音乐研究之间的关联——这种音乐以节奏与音高的解放为核心特征，这一理念在本作品以及霍普的多数创作中均有所体现。本作品的钢琴记谱法灵感源自墨尔本的阿尔伯特湖（Albert Lake），据传该湖亦是格兰杰自由音乐理论的灵感来源。
