A friendship in music

In December 2022, the Belgian musical world was shocked to learn of the sudden death of Wim Henderickx. He had earned his spurs as a composer of a great many works for orchestra and chamber groups, and his compositions for musical theatre were also applauded internationally. Henderickx was renowned not only as a composer, but also served as source of inspiration as an educator and percussionist for many students and fellow musicians.

At Henderickx’s death, several nearly finished compositions were on his desk. Music that could not be allowed simply to disappear. Diederik Glorieux, his musical right-hand man for nearly two decades, was entrusted with the exceptional task of making the works read for performance. Among the many sketches, there was also a concept for a timpani concerto, intended for Henderickx’s good friend the percussionist Gert François and the Brussels Philharmonic. From those outlines, and in close consultation with François and Bea Steylaerts, Henderickx’s widow, Glorieux finished the composition so that the work is now ready to be performed, entirely in Wim’s spirit.

There could be no better work to set alongside the première of the Timpani Concerto than Beethoven’s powerful Third Symphony, a work that Henderickx admired and from which he continued to draw inspiration.

Gert François, professor of percussion at the Royal Conservatory of Brussels and head of the timpani section at the Brussels Philharmonic, has performed and recorded many of Henderickx’s compositions. The two musicians met in the early 1980s during their studies at a masterclass by the French drummer Dante Agostini in Antwerp. That was the beginning of a warm friendship and reciprocal interest in each other’s work.

Along the way, François and Henderickx made plans to perform together. François thus wrote Raga I for percussion and two pianos in 1995, and a few years later a version with orchestra. In addition, he also appeared as one of the two soloists in Confrontations, and in 2011 performed the première of Groove! with the Brussels Philharmonic conducted by Giancarlo Guerrero. Not long after the première, Henderickx and François came up with the idea of writing a work for timpani: ‘During Reggae Geel, our annual guilty pleasure, somewhere among the trees of the dubstep forest, we speculated about how we could give further shape to that idea. We wanted to offer an alternative to the current solo literature for timpani, which – with the exception of Le Sacre du Printemps by Stravinsky – made little room for the lyricism and subtlety of the instrument. The majority of compositions are showpieces that give vent mainly to the tribal aspect and the volume. Our starting point soon became clear: the music should convey both the ritual energy and the inner poetry of the timpani.’

While François received a completed score for Raga I, in later works he was given more freedom of choice: ‘Forr Groove!, Wim gave me a score with various possibilities in matters of technique – he did not shy away from the challenge. I was able in that case to indicate what was and wasn’t feasible as a player. Sometimes we came into conflict with each other, since he had a certain musical idea in his head that for me was practically speaking unplayable. He encouraged me to work harder (laughs). But because we had such a close friendship, we were able to share our views with each other in complete freedom.’

At the beginning of the creation process of the Timpani Concerto, Henderickx tested things out with François, even though he thoroughly was familiar with the instrument. After Henderickx’s death, Diederik Glorieux, who had worked closely with him for 17 years as his assistant, took over the baton: ‘I relied on verbal agreements that Wim and I had made with each other. I shared this with Diederik, and with the input of Bea, who was Wim’s wife and business assistant and was more familiar than anyone with the typical musical structures of his earlier works, we created an overarching framework. Next, he presented me with passages and I gave him feedback, and so on. He also provided entire blocks in which I can improvise and add my own interpretation of the work.’

Henderickx drew inspiration for his compositions in religion and nature, among other things. The Timpani Concerto thus followed the structure of a Mass, and the five movements are named for the natural elements: Water, Earth, Fire, Air and Ether. His predilection for non-Western cultures and music is also strongly reflected: ‘Wim’s last works were profoundly inspired by Middle Eastern mysticism. You can hear that, for example, in Revelations and his opera De Bekeerlinge [The Convert]. In the Timpani Concerto, for example, he developed a new type of musical notation for the classical quintuplets and septuplets, giving the work a more meditative character. In the interludes with choir, he introduced the daf and the tombak, two Middle Eastern instruments that he himself played. The daf is a sort of frame drum made with a round wooden frame over which a thin animal skin is stretched. It is used among other things in Sufi music in Turkey, played often for hours at a time. The tombak is shaped like a like an hourglass – somewhat like a djembe – and is held under the arm. The two instruments require a very different performance technique and idiom that I have to make my own. Not only do they add a new colour to the sound but also inspire me to adapt this new technique to the timpani. In this way, I create a link between traditional instruments and the modern orchestra timpani.
