This particular song is written in Sonata Form. We have no singer and that's why the music is so melodic. The guitars do all of the singing. Listen to the WHOLE THING cause you really won't be disappointed! It has SOOOO many changes to keep the listener interested. From the classical melodies in the first few minutes to the medieval drumming in the middle section to the alternating solos, this piece is one of our very favorites to perform. Thanks and we hope you enjoy the sounds of Harbinger!!
