24.5 ---- build up thicknesses of counterpoint o g [?] : based on harmonic series[?] tune applied in dub-series[?] terms ?? application of time series: if poss. rather obvious to use: higher for values, longer but time. Use perhaps spectral methods including the version of this, & also the taking of the mean as longest, & the extreme pitches as shortest & v.v[?] time series: sound of silence, decide optimum range of sound, & for silence either: list these or e.g. double these quantities etc. for silence - use inverse, subtracted ratio, giving regular rhythm, or use same sound lengths, but made up to series quantities with silence. Adjust time scales to get different pace. Simple time series, not based on pitch, but based on time values in .|'s for each cluster. Use counterpoint, of clusters in pitch series, against clusters in simple series, timed to begin & end simultaneously, at different intensity levels & perhaps in different 8ve.? 1.1461 | 1.1461 | 1.1461 - | - | - 1.1506 | 1.6957 | 1.8134 ------ | ------ | ------ 0.2967 | 0.8418 | 0.9595 - | - | - 1.9031 | 1.9844 | 1.9987 ------ | ------ | ------ 0.3936 | 0.8574 | 0.9608 ------ | ------ | ------ 1.1461 | 1.1461 | 1.1461 | 1.1461 - | - | - | - 1.4391 | 1.5964 | 1.7645 | 1.8495 ------ | ------ | ------ | ------ 0.5852 | 0.7415 | 0.9106 | 0.9956 - | - | - | - 1.9416 | 1.9678 | 0.9941 | ------ | ------ | ------ | 0.6436 | 0.7737 | 0.9165 |
