The daxophone, invented by Hans Reichel, is an electric wooden experimental musical instrument of the friction idiophones category.

[1] The first usage of the daxophone in a musical work was the release of Hans Reichel's album The Dawn of Dachsman in 1987.

[1] One side of the dax is fretted according to a random logarithmic succession, while the other is left unfretted and covered with a sheet of cardboard for a mellower sound and to preserve the surface.

Plans are downloadable from his website, with a collection of proven shapes for the tongue delivered in the file format of a font, thus playing on Reichel's other profession as a typeface designer.

[4] The frequency interval between each fret in the succession will change due to the difference in pitch range between tongues, which is why the unfretted side is more frequently used for playing tonally in known compositions.
