Pulse Tubes
Pulse (or wah wah) tubes are unique musical instruments suitable especially for music therapy and playing with music, music communication and the joy of sound creation. They are precisely tuned metal tubes that start sounding by the strike of a mallet and their sound can be then formed and changed in very interesting way by covering and uncovering the small hole by a finger. They are available in various sizes and precisely tuned - so they can also be used by playing together. It is a great fun too.
