During the development of this album, Tournier remarked it almost felt like a trio sonata for 2 flutes and electronics, pointing at the closely knit counterpoint in sounds and pitches resulting. In fact, the work combines a classical sense of form, at the same time rigid and clear, as well as open and flexible, with the improvisatory element added. Classical then has to be interpreted in both the European and Indian sense, and this form bridges formal principles shared and developed along different styles across two continents. Existing forms were not literally used, forms such as the classical European song-form, rondo, or sonata from types with their clearly outlined sections and repetitions, depending on functional harmony to work, nor is there literal use of the classical Indian forms, depending on the gradual build-up in speed, register, and intensity, all to a single drone tonic. The Dronescape Oneirology is a far more adventurous and moving drone, in sound, dynamics, pitch content and form, and is not treated as background or accompaniment, but interacted with to create a larger story.

The work Jñāna – Rigpa is exploring the boundaries of autonomous drone composition, both in the sense of its duration (it has the longest single-track duration streaming platforms allow today), as in the sense of its minimalism of musical and technical means used. While creating an atmosphere of almost trance and meditation, it also serves as a means, a tool, for deep and inner reflection. Reflection on one’s own hearing is intended explicitly here: a music that serves to listen to one’s own hearing.

In Peter Brook’s 1979 film Meetings with Remarkable Men there is a scene in which musicians will attempt to produce a sound that will make the stones of a valley vibrate. In this re-enacting of a famous scene from Gurdieff’s memoires, Kudsi Erguner is one of the musician-actors performing on the screen. In the movie (and in the book), it is in fact a singer that finally succeeds at this, not the Ney. Oneirology 2 can perhaps be regarded as the ultimate attempt to amend this 42-year-old “failure” and enable Erguner’s Ney to finally accomplish this mythical task of producing a music with sounds that will eventually set a complete mountain valley into total vibration, this time in cooperation with van Dillen’s electronics/digitalics.

Myrmecology consists of a variety of simultaneous rhythms, working as polyrhythms, in six proportional tempi. These rhythms make up a variety of cycles by means of moving, changing, and developing, ostinati. Furthermore, these polyrhythms are enhanced by use of both binary (also quaternary at times) and ternary feel, as well as of microtiming. Microtiming is the rhythmic equivalent of the harmonic concept Microtuning, but the first is related to minute but precisely controlled differences in timing. The inspiration for this treatment of rhythm and polyrhythm can be found in various worldwide music traditions originally stemming from the African continent, many of which are using rhythm and (micro)timing as a means of emotional expression, as opposed to other traditions using (micro)tuning systems and/or harmony for emotional expression. Rhythm in this way becomes a polyphony in its own right, and in Myrmecology this is explored, over its two hours duration.
