World premiere of William Susman’s Material Rhythms for percussion quartet performed by Reinhardt University’s Percussion Ensemble under the direction of Olivia Kieffer.
I recently asked composer/percussionist Olivia Kieffer to talk about her work on some of my percussion music. She and her ensemble, the Reinhardt University Percussion Ensemble, premiered my quartet Material Rhythms. She also arranged some of my piano music from the series Quiet Rhythms. -William Susman

Before we met, Bill and I exchanged emails in preparation for the premiere of his percussion quartet “Material Rhythms”. One of the first pieces of his that I listened to was a recording of Francesco Di Fiore on piano playing “Prologue and Action 1” from Quiet Rhythms Book I.

I loved it so much, and was immediately taken by the beautiful ringing tones and thought how marvelous it would sound on vibraphones and marimbas. I asked Bill if I could arrange it for a keyboard quartet of 2 vibes and 2 marimbas, and he was on board! I stayed up all night and arranged “Action” and sent it to Bill in the morning. He came back with excellent suggestions, and I let the arrangement sit for a good while.
When Bill came to Reinhardt to hear the Percussion Ensemble premiere Material Rhythms, he gave me the bound score of Quiet Rhythms, Book I. Once I had that, I was able to truly start translating the piano score into a living breathing keyboard quartet. Taking apart the notes and rhythms in each hand, sometimes keeping them the same and sometimes rearranging them, and fitting them in creative ways to the range and tone of the keyboards was a lot of fun and a new experience for me.
Turns out this solo piano music fits beautifully and naturally on marimba and vibes. Since it is less Right-Hand/Left-Hand and more Hands-Working-Together, it is physically familiar for percussionists to play.

“Prologue 1” starts with ascending and descending 16ths, and introduces the hand-to-hand clavé.

In “Action 1”, there is a constant clavé rhythm, which changes from 3/2 to 2/3 alongside the harmonic changes. It starts with a busier amount of pitches, then simplifies, then moves into big chords.

The clavé is notated in the piano score with beams that cover both staves, to make the pattern visually clear. I had to find an idiomatic way to notate this for percussionists which led me to figuring out a 4-mallet sticking that would naturally ascend like the “right hand” of the piano. Another idea was to use harder mallets in the right hand.

Letter D in Action 1 is the first time that all four parts are playing together, it’s the first time full chords appear, and is one of two spots where the vibraphones represent one hand and the marimbas the other. Though Prologue has slightly similar music in its last section; it is pianissimo and subtle. So it felt important to bring those Action 1 clavé chords in with a bang!

In Material Rhythms, each movement has its own rhythmic patterns which are passed from instrument to instrument, player to player, in various combinations. The first 3 movements are Wood (2 blocks), Metal (3 metals), and Skin (2 drums). The last movement is a combination of all 3. This passing rhythmic material creates its own melodies, particularly in “Metal”. I cut pipes to be very close in pitch to each other (in relation to low-middle-high across the players), to create a sort of Balinese Gamelan, shimmery sound. “Metal” has constant 3s, and the rhythms come out from the melodies of the pipes, and the stark dynamic contrasts.

Something I love about Bill’s music is that he is a master of layering. This is something that can be discovered while listening to the music and also from studying the score. The depth of his music comes to life, though, when being played. There are beautiful patterns which fit themselves into all the chords. Like a beloved book often returned to, and every time something new appears, so these layers are found over time by the performer. His music speaks for itself! He can create a pattern that is, in a single line, harmonic, melodic, and rhythmic. Quiet Rhythms is beautiful and uncomplicated, yet goes as deep as one is willing to take it. When the music speaks on its own, the details are fresh to see and to work with. -Olivia Kieffer
