The piece was completed in 1976 and performed for the first time in 1979 and is by far his most popular and most performed work.
The most remarkable aspect about this work is the amount of freedom that is given to the performer(s). The piece can be performed with different instruments and a different number of performers. Most commonly, it is played with either two or four pianos, but during the first performance in Bergen, North Holland in the Netherlands, the performers used three pianos and an electric organ. Other aspects which illustrate this freedom can be found in how this piece has been built up. The composer created over a hundred small cells called 'sections' of a few bars, which can be played ad libitum and be repeated either one or many more times (some bridges excepted). Because of this build-up, performance may take from some two hours to more than a day.
The piece is regularly performed live in the Netherlands with changing players and instruments, ranging from those with four pianos or one or more different instruments, to those played by a solo musician. A couple of performances have taken place with the carillon of the Dom Tower of Utrecht. It has also been performed in several public spaces all around the Netherlands, such as the Groningen railway station.
This piece is considered to be minimal in origin, because of the repetitive, obstinate, nature of the piece, but there is some discussion on this subject. Ten Holt usually uses the term 'genetic code'  to describe his work, probably because of the typical build-up of the piece. As opposed to a high percentage of modern classical music which is not tonal and/or consonant, Canto Ostinato contains tonal harmonies and does not become (very) dissonant. Another typical aspect is the fact that one can hear the same or similar bass figures and harmonies throughout the piece, which explains the title. If one word would have to catch the essence of Canto Ostinato, one could use "meditative", as the different sections are similar, but generate different emotional reactions.
Examples of pieces written by Ten Holt in roughly the same way are Lemniscaat (1983), Horizon (1985), Incantatie IV and Meandres (1997), none of which has become as popular as Canto Ostinato.

Many different recordings of Canto Ostinato are now available. The CD recording made by Kees Wieringa and Polo de Haas, published in 1996 by Emergo Classics, received Gold status, which means that more than 10,000 copies have been sold (the actual number lies above 15,000). That is rather rare for modern classical music performance CDs and especially for Dutch composers, who usually do not generate that much popularity. Another recording which is relatively popular is the four piano version of the Piano Ensemble, featuring Irene Russo, Fred Oldenburg, Sandra van Veen and Jeroen van Veen and published by Brilliant Classics. One particular record was made by Ivo Janssen, published in 2009, which total length is around 60 minutes. It's a one man, one piano, performance of the original composition.
Versions using other instruments than piano include: solo organ (performed by Aart Bergwerff in 2007), solo harp (by Assia Cunego, Italy, in 2009) and solo marimba (Peter Elbertse, 2012). Cunego's performance inspired Dutch pianist Ivo Janssen to record a one man version for solo piano in 2009. Other versions use combinations of piano, organ, marimba, carillon and other instruments.
