TILEWORK Series of Fourteen Solo Pieces
How can different rhythmic patterns be combined in such a way that no two patterns ever occur simultaneously and every beat is filled? "Tiling the line" is a subject that Johnson and several mathematicians have been investigating (see the text from the IRCAM MaMuX lecture "Tiling the line in theory and in practice (In theory / In practice) of February 2002), and the original Tilework series, published in 2003, consists of 14 pieces for solo instruments, that employ these techniques: Tilework for Flute, Tilework for Oboe, Tilework for Clarinet, Tilework for Bassoon, Tilework for Saxophone, Tilework for Horn, Tilework for Trumpet, Tilework for Trombone, Tilework for Tuba, Tilework for Percussion Solo, Tilework for Violin, Tilework for Viola, Tilework for Cello, Tilework for Double Bass.
New pieces of TILEWORK
Tilework for Piano
Premiered in June 2004 by John McAlpine, this composition tiles a line of 15 points with five voices in tempos 7 : 5 : 4 : 2 : 1 and lasts about 10 minutes. It is a structure known as a "perfect tiling," and one may read about this the article about Tom Johnson's music in the magazine Pour la Science (novembre 2004).
Tilework for String Quartet
Tilework for String Quartet is a compilation of all the ways one can tile a line of 12 points by overlapping a single six-note rhythm. The four musicians play these rhythms in canon for 10 minutes in a rapid music requiring great precision. The work was premiered in a KlangAktion concert in Münich in December, 2004.
Tilework for Log Drums
Tilework for Log Drums is in seven sections, showing the seven possible solutions for tiling a line of 18 points with six voices, each voice inserting three notes in one of five tempos: 1 : 2 : 3 : 4 : 5. I wanted to hear the music played on log drums mostly because I like the sound of these instruments, but also because the notes of log drums tile the playing surface a bit the way the rhythmic tiles cover the 18-beat phrases in this piece. I can imagine the music played as a virtuoso solo, though the counterpoint will be clearer, and the rhythm will flow more smoothly, if played by an ensemble of two to six musicians. The score was originally published as Tilework for Five Conductors and One Drummer, no longer available.
