Pulse Tubes

These special-effect instruments create a rhythmic pulsing sound as the resonance hole is opened and closed. By adjusting the movement, the pulse can be gently accelerated or slowed, offering a flexible way to shape tempo and atmosphere.

Used as simple tuning tools, they introduce a sense of motion and variation into sound work. When applied as an octave set, they can also be explored as chakra pulses, supporting focused listening in practices involving subtle energy centers.
