Jaap Blonk (born 1953 in Woerden, Netherlands) is a self-taught composer, performer and poet.
His unfinished studies in mathematics and musicology mainly created a penchant for activities in a Dada vein, as did several unsuccessful jobs in offices and other well-organized systems.
In the late 1970s he took up saxophone and started to compose music.
A few years later he discovered his potential as a vocal performer, at first in reciting poetry and later on in improvisations and his own compositions.
From around the year 1995 on Blonk started work with electronics, at first using samples of his own voice, then extending the field to include pure sound synthesis as well.
He took a year off of performing in 2006. His renewed interest in mathematics made him start a research of the possibilities of algorithmic composition for the creation of music, visual animation and poetry. 
 
As a vocalist, Jaap Blonk is unique for his powerful stage presence and keen grasp of structure, even in free improvisation. He has performed around the world, on all continents. With the use of live electronics, and sometimes projection of visuals, the scope and range of his concerts has acquired a considerable extension.
 
Blonk’s recorded / published output comprises some 60 titles: CDs, vinyl, books and cassettes. 
From his sound poetry scores he developed an independent body of visual work, which has been exhibited and collected in books.
