Instruments and ensembles
Besides the multiple ensembles including the Kulintang, the most interesting musicla instruments are the ones of the multiple ethnic tribes.
So far, only two instruments are in my collection:

o the Faglung boatlute
o the Kubing mouth harp

Anyway, You can find some descriptions of instruments on the pages of Hans Brandeis:
