If you listen to this song, there's a high note repeated on every odd beat (it starts after a while).. it sounds very reverberated.. i don't understand what that instrument is.. http://www.youtube.com/watch?v=BkC5zMMifr8 maybe that effect comes from more than one instrument, (drum + woodwind ?) I have no clue, any idea is appreciated, even if completely wrong :) bye
