Schlagwerk - HRS7-432 Hand Tubes 7 Tones 432Hz

The Schlagwerk HRS7-432 Hand Tubes 7 Tones 432Hz builds its soundscape on a simple foundation: a fundamental frequency of 432 Hz, which serves as the basis for everything else. This pitch has not been chosen at random; it follows the natural laws of vibration, the same laws that govern the relationships between notes in nature. Each tube adds a layer to this structure: a harmonic of the fundamental that can be played in its own right, a layer from the pure series of natural harmonics that stacks up without ever masking the base note.

The aluminium tubes are crafted to maintain this pitch consistently, tube after tube, note after note. The surface treatment applied to each tube minimises interference and keeps the sound clear, even after long playing sessions. Holding the tube by hand allows the wrist to control the speed of oscillation – a simple gesture that alters the perceived timbre.

Whether in a percussion session, a sound bath or a meditation accompanied by sound therapy, this set from the Hand Tubes range is ideally placed at the centre of a circle or near a practitioner. The MA102 mallet, included as standard, provides the attack needed to reveal the full harmonic range of each tube without straining the hand. The partial tones vibrate simultaneously as soon as a natural tone is produced and are perceived as a single note – an acoustic phenomenon that gives the instrument its unique texture, somewhere between percussion and a bath of frequencies.
