Description
At the suggestion of the wonderful Kuss Quartet, I am returning after a long absence to the genre of the string quartet – that chamber music ensemble which, with its intensity, homogeneity, and inexhaustible sonic diversity, has for centuries been regarded as a unique realm of musical thought.
The title Cahier des équilibres mouvants (Notebook of Shifting Equilibria) – refers to a formally interlinked collection of constantly transforming musical states.
The starting point was the idea of ecological equilibrium. It describes how ecosystems, in which species coexist with other species and their environment, are organized in a state of stability. However, ecosystems are not immutable: disturbances and unexpected chain reactions can occur, although ecosystems usually recover to a state of ecological equilibrium – one that need not correspond to the initial state. This topic, in all its complexity, is particularly urgent in times of global warming and the worldwide destruction of natural habitats.
This metaphor – the transformation, the mixed state, the precarious stability of an ecosystem – fascinates me immensely from a compositional perspective. I envision the string quartet as a complex, resilient system: four closely interconnected voices capable of reacting to one another in sensitive, elastic, and unexpected ways. Disturbances and shifts are inherent to the nature of this system; equilibrium does not arise as a state of rest, but as the result of constant adaptation.
The five-part work (I: approx. 8' – II: approx. 3' – III: approx. 2' – IV: approx. 4' – V: approx. 1') therefore follows less of a linear progression and instead consists of a network of transitions, transformations, and intermediate states. Textures emerge, condense, lose their balance, and find new forms of stability – equilibria that exist only temporarily and change again in the very next moment.
In this sense, Cahier des équilibres mouvants is conceived as a musical exploration of processes of transformation, adaptation, and coexistence: a sonic notebook of fragile systems, wavering stabilities, and productive tension between order and change.
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.
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.
