Tonus is an ensemble project formed by Dirk Serries, focusing on the improvised relationship between sound and silence, often based upon a graphic score. It originated in 2017 at Serries' residency at Jazzcase in Limburg, Belgium, for which he brought together a sextet to work around a slow piano motif by Martina Verhoeven.
The literal translation of Tonus is muscle strength, but in this context defines a musical system that places equal importance on the space between notes. Both definitions apply here as the music is an exercise in discipline and anticipation while controlling the clarity, sustain and effect of each single note played. Tonus acts as a vehicle to explore and perform these exercises, as well as a general classification for his ongoing study in minimalism and free improvisation.
Monograph 50 captures a two-set sextet performance at De Singer in Belgium organised to mark Serries' 50th birthday. Joining Serries on guitar and accordion are: Patrick De Groote (trumpet), Nils Vermeulen (double bass) Benedict Taylor (viola), Colin Webster (alto sax), and Martina Verhoeven (piano).
