With five double string and two heart-shaped openings, the Viola de dois Corações or Viola da Terra is a traditional 12 strings instrument from Azores. With slight changes between the ones made in the island of Sao Miguel and Terceira, the guitar finds its roots in the fado's famous Portuguese guitar, the Guitarra Portuguesa.
The popular sayings explain that the two hearts used as the guitar's central mouth instead of a single opening stand for the love of two people living apart. Associated with the Azorean emigration period, these hearts are united by a small line representing a naval string attached to a teardrop symbol, representing "Saudade" - the feeling of missing someone.
It's also common to find in their drawings references to natural elements or Azorean traditions, depending on the feelings of the player. Used to play popular songs at local celebrations and associated with fado music with themes around love and care, it is not an easy instrument to play, but certainly a good one to listen to.
