Sonoritas - Jan Van der Roost

Sonoritas was commissioned by the Kaohsiung City Wind Orchestra, a professional wind orchestra from Taiwan. The work premiered on 10 September 2023 in the beautiful Kaohsiung Weiwuying Concert Hall, performed by the same orchestra and conducted by the composer. This impressive hall holds the largest concert organ in Asia, inspiring the composer to grant this majestic instrument a role in the composition - albeit ad libitum. Accordingly, all the important passages have also been provided for woodwind or brass instruments, so that the work can be performed with or without an organ.The title Sonoritas reflects the musical content, the rich timbres and sounds of both the wind orchestra and the organ being fully employed in this dynamic composition. A chorale melody with expansive chords opens the work and culminates in a driving theme presented by the brass instruments in various registers. The woodwinds, in turn, introduce a virtuoso saltarello-like theme, followed by a development of all these thematic elements in various forms and combinations. The work concludes grandly with an organ-like finale and, as a high point, a sonorous final chord, which crowns this wonderful sound piece with its broad lines and full harmonies, as well as rhythmic and technical fireworks.
