this and that
now the chord variation is awesome. the drums and synths are mixed nicely. also the happy tone of the song is consistent. however, the beat of the drums is predictable. and often times in the trance genre i hear the tom and cymbal mixture around 1:40 too often.
the progression and chord variations is what i've always wanted out of a trance song! this shows extensive craftsmanship on the part of the creator! so i hope you will continue! and for the rest of us keep playing with musical theories that are new to you, it'll result in awesomeness for us all! :D
