As its name implies, a tubofone is an instrument composed of one or more tubes, and these may be impacted over the body, longitudinally or at the top, using the tube as a sounding board for only one fundamental frequency: the corresponding to their length. By striking the top of the tube, this means that each tube promotes only two notes, with a pure octave interval between them, either be open or closed at the end opposite to the impacted. The Tubofone MISSOM® is manufactured in two versions: one for teaching (made in PVC) and other in Hard Maple wood. This instrument is tuned taking into account the equal temperament, with reference there to 440Hz. The sets are sold in accordance with the wishes of the customer and may be sold in sets chromatic, or loose. Dimensions of length between 500mm and 1500mm.
