Didgeridoo Low Tone Conical are conically shaped didgeridoos. This means that the diameter of the didgeridoo gradually widens to the bottom. The low tone didgeridoo measures 1.45 to 1.60 metres on average, which is longer than the average cylindrical didgeridoo in the same key or tone. They are often very straight in shape, although a slight overall curve may occur among those from bloodwood. All low tone conical didgeridoos have medium-sized mouthpieces and are usually made of stringy bark, bloodwood or woolly butt eucalyptus, but can just as well be made of boxwood or ironbark eucalyptus. Key's or tones range from B to D.

Conically shaped didgeridoos can be distinguished from other types of didgeridoo by their superior sound. Conical didgeridoos have a wider range of sound; a deeper, fuller bass and clearer, more pronounced high tones. The gradual shape of the inner column amplifies and harmonizes the sound of the didgeridoo, which has a positive effect on playing techniques using vocal and throat sounds. Furthermore, conical didgeridoos produce a larger amount of trumpet tones with less effort. Because the inner column of conical didgeridoos give more back pressure, circular breathing becomes easier to uphold. Therefore, more complex breathing patterns and more advanced didgeridoo playing techniques are easier to accomplish.
