It matches the standard tuning of a 12-string guitar, one octave lower. The tuning of these instruments is (capital letters are an octave lower than small

The high string tension makes the instrument almost implayable for beginner students, especially for children, and additionally serves to spoil the ear training for harmonies and tone intervals due to intonation errors. Luthier intervention is required in such cases. High string action at the nut is often preferred to avoid string buzz with heavy playing style. The lower fret area is therefore out of tune.
