On Sunday, November 22nd, Harmony welcomes a special performance of Canto Ostinato for six grand pianos led by Jeroen van Veen. Sonja Lončar and Andrija Pavlovic of LP Duo, Mike del Ferro, Tamara Rumiantsev and Irene Russo, will play on his side. The six-piano version of Canto Ostinato has not been performed in concert since the passing of Simeon ten Holt, making this a rare premiere. For more than fifteen years, Jeroen van Veen has been performing immersive lying-down concerts around Simeon ten Holt’s Canto Ostinato. Over the years, he has performed the work more than 400 times in countless formations. His pioneering “Ligconcert” theatre tour travelled throughout the Netherlands in 2010–2011 with 89 Canto Ostinato performances, followed by acclaimed editions at venues such as the Beurs van Berlage, the Concertgebouw, the Scheepvaartmuseum Amsterdam, and the Werkspoorkathedraal in Utrecht. Canto Ostinato was composed between 1976 and 1979 by Simeon ten Holt and has since become one of the most iconic works in Dutch contemporary classical music. Written for multiple key instruments, the composition is built from repeating musical cells that slowly evolve over time. Rather than being fixed, the structure leaves space for performers to decide in the moment how long sections are repeated, allowing every performance to unfold differently. The result is an uninterrupted and meditative listening experience in which time and subtle change become central elements of the music. Simeon ten Holt was one of the Netherlands’ most influential contemporary composers. Born in 1923 in Bergen, he developed a highly personal musical language that moved beyond traditional classical structures and became closely associated with minimal music. Through works such as Canto Ostinato, he introduced listeners to a new way of experiencing classical music. Jeroen van Veen shared a close artistic friendship with Simeon ten Holt and became one of the composer’s most devoted interpreters. Over the years, Van Veen performed and recorded Ten Holt’s music extensively, helping introduce Canto Ostinato to audiences around the world. The two spent many hours together discussing music, interpretation and structure. Through countless performances and recordings, Jeroen van Veen plays a significant role in carrying Simeon ten Holt’s musical legacy into a new generation.
