How the octophone makes its sound
In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the octophone belongs to the lutes: strings run parallel to a soundboard and along a neck – the family of the guitar, violin, sitar and oud.
More broadly it is one of the chordophones (string instruments), where sound comes from vibrating strings, amplified by a resonating body.
Its timbre – the colour that lets you tell it apart from other instruments playing the same note – comes from the mix of overtones its body and resonator emphasise.
From Wikipedia
The octophone (or octofone) is a stringed musical instrument related to the mandola family resembling an octave mandolin. It was marketed by Regal Musical Instrument Company, who introduced it 21 January 1928, as an "eight-purpose instrument".
The name "Octophone" came from the idea that the instrument could take on the "tone combinations" of eight instruments, the tenor guitar, tenor banjo, ukulele, taro patch, tiple, mandolin, mandola and mandocello. Changing from one instrument to another was a matter of changing the tuning. The instrument came with an instruction book that told owners "how to use, how to tune and how to play" the instrument
