The Cadeironcello is an innovative tool designed by MISSOM®. This is one set stylized, where we can find several tools coupled, but it is not easy to characterize it. This musical chair includes a drum wood at top, one adufe skin and 10 strings on the back. This set of strings allows them to be individually rubbed with a bow or plucked, ranging from the low strings, cello, guitar and ukulele. It comes with a tuning system for tuning pegs. This instrument was produced to Drumming GP, for the event "Art On Chairs" in Paredes, Portugal (Nov/2012).

The wood-block, block of wood or Chinese box (in the toolbox Orff), is a musical instrument made of wood of a solid body with a longitudinal slot, which can be produced in various ways. The Wood-Blocks MISSOM® are cobbled, and have the particularity that they may be retuned, in the case of a well defined idiofone tall. The Wood-Blocks MISSOM® can also be produced in various woods, but hard-maple is being the most used and that offers better results from low to high consistency, and constancy enough on its density, allowing better control tuning. These instruments can be sold loose or in sets of five units, ready to be played in sets multipercussão as in works like 'Rebound' by Iannis Xenakis. Parallelepiped dimensions varied between 2,36 X 2,76 X 2,36 X 5,12 inch and 4,33 X 12,8 inch.

Built in 0,47 inch birch plywood, the Cajon MISSOM Kids ® was designed with kids in mind, adapting it to an instrument didactically easier to use. The Cajon is an instrument that originated in Peru in the colonial era and was developed by enslaved African cultures. At that time, were seized boxes and drawers to make this instrument, which became the primary rhythmic accompaniment of popular tunes.

Unlike what the name implies, the Log drum is a drum, has no skin. It is a tribal idiofone roots, where the blade is impacted (often in the form of tongue) and is coupled to the resonance box. Around the world were found similar instruments, in various formats, making it impossible to decide their origin. In older instruments is common that the instrument is constructed in one piece. In the latest case, the struck zone is commonly designed in denser woods, and resonance boxes of wood lighter, thus helping the role of each, and also enabling greater control of pitch. LOG DRUM MISSOM® is generally parallelepiped in various sizes, depending on the number of notes and pitch desired, up to six blades per box, and can be built individually, note by note.
