Composer note
Moireen is a reduced version of Moire , especially made for F-Plus on the occasion of their appearance at PASIC in 2026.
Moire might be considered an Irish name, or at least a variation on one. I suppose I have form in writing pieces with real names, such as Paddy, Bridget, etc. So I like naming pieces. But moire could also refer to moiré, the optical illusion that happens when two similar patterns collide or are overlaid. This collision of similar materials to produce a new perceptual disturbance or frisson not explicitly there in the notes themselves is a driving idea of this piece. I make little progressions or processes where the pitches or rhythms tend towards something, but they do it in different ways and then these are superimposed on top of each other. The approach is like a canon in that it plays with something new being created out of the superimposition of similar material, but here it is rarely delayed , and the little changes between the similar-ish material create interesting glitches on the surface that add to the moiré effect, often compounded by oscillating pulsing glisses that merge between the cracks of the varied but similar material. Sometimes, one instrument is doing a quantized version of the other: where the violin is glissing between nodes on the harmonic series, the clarinet is leading to them in a terraced fashion while the vibe is only hitting on the closest equal tempered equivalent. Ultimately this patterning is a way of creating a kind of vibrating organism that somehow transforms and goes beyond the three individual instruments. Together, more is possible, as it were.

Publishers use a lot of words to describe what they sell, and we know it can be confusing. We've tried to be as clear as possible to make sure you get exactly what you are looking for. Below are descriptions of the terms that we use to describe the various formats that music often comes in.
Choral Score
A score for vocalists that only contains the vocal lines. The instrumental parts are not there for reference. Generally, cheaper than a vocal score and requires multiple copies for purchase.
Digital Download
Digital, PDF version of the score.
Facsimile
Reproductions of the original hand-written scores from the composer.
Full Score
For ensemble music, this indicates that the edition contains all parts on a single system (there are not separate parts for each player). In larger ensembles, this is for the conductor.
Hardcover
Hardbound. Generally either linen-covered or half-leather.
Orchestral Parts
Similar to a wind set, this is a collection of parts. In the case of strings, the numbers listed are the number of copies included, though generally these are available individually (often with minimum quantities required).
Paperback
When publishers offer multiple bindings (e.g. hardcover) or study scores, this is the "standard" version. If you're planning to play the music, this is probably what you want.
Performance / Playing Score
A score of the music containing all parts on one system, intended for players to share. There are not separate parts for each player.
Set of Parts
For ensemble music, this indicates that there are separate individual parts for each player.
Solo Part with Piano Reduction
For solo pieces with orchestra, this is a version that contains a piano reduction of the orchestra parts. For piano pieces, two copies are typically needed for performance.
Study Score
A small (think choral size) copy of the complete score meant for studying, and not playing. They make great add-ons when learning concertos and small chamber works.
Vocal Score
A score prepared for vocalists that includes the piano/organ part or a reduction of the instrumental parts.
Wind Set
For orchestral music, this is a collection of wind and percussion parts. The specific quantities of each instrument are notated.
With Audio
In addition to the printed music, the edition contains recordings of the pieces. This may be an included CD, or access to files on the internet.
With / Without Fingering (Markings)
Some publishers prepare two copies - a pure Urtext edition that includes no fingering (or bowing) suggestions and a lightly edited version that includes a minimal number of editorial markings.
