‘January ’94’ for a percussionist with a compact set of instruments, is a very clear sounding work, written according to an exquisitely simple process.
The player uses two timpani with calf skins, tuned to an identical pitch. The left hand operates one timpano, the right hand the other. Sounds are extracted from the timpani by means of felt, rubber, wood, hands and fingers.
For each of these five ‘sound generators’ there are five articulations, or ways of touching the timpani: staccato attacks, attacks without resonance, attacks with resonance, stroking in a straight line and stroking in a circular line. All twenty-five resulting sound colours are actually used in the piece.
For both the left and right hand, Hoenderdos composed two rows, one concerning the order of sound generators and one concerning the order of articulations. Since the left and right hand rows have different lengths, the combinations of sound generators and articulations are always different. Also, the right hand performs the material at a much slower tempo than the left hand. After a certain number of repetitions, different for the left and right hand, all four rows finish more or less at the same time.
Though this process seems quite technical, it results in a piece that appears to deal chiefly with subtle variations in sound colours. In addition, the often rapid changes of sound generators and articulations bring about a degree of virtuosity.
