I have in mind a revision to try out and may post a new version at a later date. I’m also working now on Variations 27-32, which are a group of interconnected variations approx. 1 hour in duration. They share many of the same qualities of Variation 26, including the same basic rhythmic grid.  

A microtonal canon. While listening, I was reminded of a few photos I took of a pretty sunset through a train window last winter, particularly how the sunset and the reflection of the inside of the train got warped together in the photos.

Landform Variations (LFVs):

The Landform Variations are not sonic representations of specific landforms or topographical formations (i.e. mountains, caves, dunes, valleys, etc.). However, some attributes of natural terrains and the variety of life they support have conceptually influenced the form of these pieces. The concept of an ecotone was also of interest to me in writing these pieces. An ecotone is a transitional area between two (or more) environments that features attributes of both, sometimes with unusual overlaps in geology, fauna, and flora.

Different combinations of a relatively small set of natural conditions (mineral and soil composition, altitude, temperature, water/humidity, sunlight etc.) account for a huge variety of differences (as well as similarities) in landscapes and the fauna and flora they support. This can be seen on a subtle level on a walk in a mundane local park or on a magnificent scale in national parks. Where erosion has created awe inspiring formations (Grand Canyon, Carlsbad Caverns, Arches, etc. ) or conditions support clusters of highly unusual and specialized plant life (Sequoia, Joshua Tree, Seguaro, etc.), these natural features have combined in startling combinations.

In recent years, I have sometimes used the metaphor of topographical variation as a loose model for creating a variety of sonic textures within a musical work. Thinking about sound in this manner helps suggest how a piece may vary over time and what musical features it would support (in ways unobtrusive, brazen, or awkward). The Landform Variations were not written in traditional theme-and-variations form. They do not even have a theme; instead 38 of my favorite pentatonic (5-note) scales are juxtaposed. The proportions of consonance and dissonance in these scales suit one of my aesthetic goals – producing music which has few cultural and emotional reference points (that I’m aware of). Therefore these scales are (for the most part) not very reminiscent of more familiar scales (i.e. major, minor, chromatic, whole tone, blues, church modes, and popular/stereotyped “world music” scales and modes). Each “book” of variations highlights a different way of combining these scales based on shared attributes. The variations in Book 2 feature combinations of scales which share a specified degree from the tonic.
