When a person looks at or listens to something, their eyes and ears pursue things, they get stirred up, only to stop when things are gone. This activity and rest are all subjects, but the heavenly ruler becomes their slave. This is living with demons. But now if you make yourself live with a human being in all activity and rest, this human being is the heavenly ruler, who is a real human being. If when he moves, one moves with him, then the movement is the Heavenly root. When he rests, one rests with him; this is the rest of the moon cavern. Even when he alternates movement and rest for no clear reason just go along with him. When he rises and falls, rise and fall with him. That is what is called going to and fro between the root of Heaven and the moon cavern without occupying oneself with other things. (Tai Yi Jin Hua Zong Zhi / Part 8. A Secret Spell for Freedom / Section 9)

The second volume of the "Trigonometric Meditations", like the first one, uses numbers related to the circle of angles. But instead of using values from units of angular measure (i.e. Degrees and Radians), this time Āryabhaṭa's sine table is used. It is a set of twenty-four numbers given in the astronomical treatise Āryabhaṭiya, composed by the fifth century astronomer Āryabhaṭa (476–550 CE), for the computation of the half-chords of certain set of arcs of a circle. Āryabhaṭa's jya values become the pitch series and with a SC code like this:

{SinOsc.ar([225,224.8560],0,0.1)*EnvGen.kr(Env.sine(3.45))}.scope

the difference between Āryabhaṭa's jya values and the modern jya values create a phase effect which lasts for the amount of time identical to the Angle (In Degrees and Arcminutes, treated as Seconds And Milliseconds time). So, for example the Si No 1 is a phasing of 224.8560 Hz and 225 Hz with a accompanying 225 Hz on Pd.

Cy-Ens is a computer music project from MP|vH+ CSAP with the ambition of expanding the potentials of understanding the æsthetics of computational sound and appreciation of logic, math and art. With continous works like "Aryabhatia : Trigonometric Meditations", "Tai Yi Jin Hua Zong Zhi" and "The Tower of Hanoi", Cy-Ens explores logical art, to inspire learning and personal development, and to create art.
Regarding the musical direction, Cy-Ens usually performs works based on an analogy. Music is viewed as a conceptual metaphor with various mathematical material as source domain and systematic sonic structure composition as the target domain. This is the process of generating or composing abstract, conceptual, mathematical and musical models of sound based on numbers and patterns of other conceptual domain. Patterns of musical form, musical structure and design arise from the logical relation of the target domain's components and their interdependence. 

Cy-Ens performs music mainly using free and open source audio programming languages. (Sometimes beside the audio programming languages, digital gadgets such as Nintendo DS, iPad, etc., various types of MIDI controller such as sliders, knobs, percussion pads, and various software synthesizers, samplers and digital audio workstations may appear in the band's works.)
