chromaticism
English era
Definition
The use of notes outside the diatonic scale of the prevailing key, creating harmonic colour and tension. In the 20th-century context, intense chromaticism often destabilises tonal centres entirely. Gubaidulinas piano works use chromatic saturation as an expressive force — dense chromatic clusters in the Sonata, chromatic ground in the Chaconne — rather than as ornamental colouring.
Interpretive Guidance
In Gubaidulinas style, chromatic dissonance carries emotional weight: it is not to be softened. Lean into half-step clashes and allow dissonant simultaneities to project; resolution, when it comes, gains meaning from the sustained tension that preceded it.
