The main traditional instruments of Leros are:
Tsampuna or Tsambuna: A predecessor of the bagpipe, this is made out of a goats stomach and its a difficult instrument to play as it can only produce 6 notes. Therefore it requires great skill and lots of practise in order to master.
Tsantouri or Santouri: Made of pine or walnut wood this instrument has a very sweet and unique sound.
The Lerian Lyra: Although originally of Cretan influence it has a slightly different sound from that of the Cretan or Pontiaki Lyra. In my opinion the main difference is the box which is wider than other Lyras, I could be wrong though....
There are other instruments also used such as the violin, laouto, accordion, but the three described above are the main traditional musical instruments of Leros.
