Main characteristics of colotomic form
Cyclical Structure (Cyclical Structure)
Music consists of repetitions of short or long rhythmic cycles (metric cycles of 2–256 beats).
At the end of a large cycle, the deepest enormous gong (Gong Ageng) sounds, marking a division.
Hierarchical time division (Hierarchical Time Marking).
Particular gongs or metal percussion instruments strike different beats at different speeds.
Large gongs group instruments playing fine subdivisions (ketuk, kempyang, etc.), organizing structure like punctuation.
Colotomic instruments (instruments marking divisions).
The slowest pulses (longest cycles) are handled by low gongs, fast pulses by small gongs.
Main instruments: Gong Ageng (huge gong), Kempul (suspended gong), Kenong (large horizontally placed gong), Ketuk/Kempyang (small metal percussion instruments).
コロトミック形式の主な特徴
循環する構造 (Cyclical Structure)
音楽は短く、または長いリズムサイクル(2〜256拍のメトリック・サイクル)の繰り返しで構成される。
大きなサイクルの最後に、最も低音の巨大なゴング(Gong Ageng)が鳴り、一つの区切りを示す。
階層的な時分割 (Hierarchical Time Marking)
特定のゴングや金属打楽器が、異なる速度で異なる拍を打つ。
細かい音符を刻む楽器(ketuk, kempyangなど)を、大きなゴングがグループ化し、句読点のように構造を整理する。
コロトミック楽器(区切りを刻む楽器)
最も遅いパルス(最長サイクル)は低音のゴング、速いパルスは小型のゴングが担当する。
主な楽器:Gong Ageng(巨大なゴング)、Kempul(吊るされたゴング)、Kenong(横に置かれた大型ゴング)、Ketuk/Kempyang(小さな金属打楽器)
