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

### 节目说明
本作曲旨在通过音高追踪与频谱滤波技术，尽可能贴近珀西·格兰杰（Percy Grainger）的自由音乐理念音响效果。细腻疏朗的钢琴音高被采样并转换为类似特雷门琴（theremin）的音色，此时十二平均律的约束不再适用。“Kaps钢琴”是珀西·格兰杰的童年用琴，现收藏于墨尔本珀西·格兰杰博物馆，1887年于德国德累斯顿制造。格兰杰童年时期在其教师兼母亲罗斯·格兰杰的陪伴下，每日使用这架钢琴练琴。
作曲家霍普（Hope）长期着迷于格兰杰的自由音乐理念，曾成功演绎过多部特雷门琴作品。《Kaps Freed》意在构建其童年练琴日常与后续对自由音乐探索之间的关联——这种音乐以节奏进程与音高的解放为核心特征，这一点在本作品以及霍普的多数创作中均有体现。本作品的钢琴记谱灵感源自墨尔本的阿尔伯特湖（Albert Lake），据称该湖亦是格兰杰自由音乐理论的灵感源泉。
