The subcontrabass flute is a member of the Western concert flute family.

With the length of tubing ranging from 4.6 metres (15 ft) (when in G) to 5.5 metres (18 ft) long (when in C), it is the second largest instrument of the family after the hyperbass flute.

At present, the subcontrabass flute is only available as custom order from specialty makers such as Eva Kingma or Kotato and Fukushima.

Higher quality instruments are made of silver- or chrome-plated metal, although polyvinyl is also commonly used.
