Lyras and kanteles are simple musical instruments, which have been very sought-after and used in various forms of music therapy and creative music communication. They consist of a shaped wooden body and various number of strings.
You can play them in various ways - simple melodies, melodies with accompaniment or also a full overwhelming spheric "harp" sound on all the strings at once. The most "difficult" thing usually is to tune them well and then they more or less play on their own as a sweet reward :)
