The attempt to stretch the concept of irama by exploring the liminality between pulse and noise is at the heart of this piece. This idea, coming from Central Javanese gamelan, organizes the temporal density within a piece; starting from irama lancar with one saron panerus beats per balungan notes, to irama rangkep with sixteen saron panerus beats per balungan notes. Hyperkembangan is based on a central question: what would the sound of an extremely high level of irama be, where the balungan notes is imperceivably sparse, while the elaboration is extremely dense? This hypothetical situation leads me to conceptualize a piece based on a progression from pulse, to complex sound (represented by spectral harmonies), to noise—noise here functions as a representation of an overload in the elaborative part. The piece is played with two gendèrs with pair tuning consists of customized 14-notes system that could accommodate spectral harmonies (based on the spectra of note 1 in gendèr struck with hard mallet) and its various manipulations. The "X" in the title—as well as a reference to Boulez's "Polyphonie X"—suggests a kind of cultural defacing, where new content is imposed on the cultural memory of the music, yet still maintains parts of those memories; a form of a musical palimpsest.

Here's another little demo playing around with the "anti-harmonic" idea, but instead of using an equal temperament, I took the "pseudo-octave" of 1+phi and linearly divided it into 12 linear divisions in Hz. This is similar to the "primodal" approach from Zhea Erose but technically these aren't actually harmonics in the series.

This is a really bizarre tuning - pretty much deliberately bizarre - which is "the opposite of Just Intonation." The timbre here is built on the golden ratio, which is often called the "most irrational number": if the first harmonic is called "1", then the second harmonic is 1+phi, the third is 1+2*phi, etc.

This tuning is derived from harmonics 12-24 from this antiharmonic series.

A song about the doves that I encounter where I live. The guitaroid and bass guitaroid are tuned to 26 equal pitch divisions of the octave (26ed2 for short).
