Though it seems reminiscent of alot of genres out there, this entire piece feels a bit random. To be truthful, even though this piece was likely meant to sound like it was orchestrated or simply classic, the instrumental were incredibly electronic sounding, this caused likely by having a single sound sample (instrumental voice) being modulated into different pitches and octaves, that ruins the sound quality.
Though it takes a bit more effort to do, I highly suggest you find samples that have the entire scale of a single instrument and use a program that allows you to set different keys to those specific sound samples. (A key will play A, B will play B, this is including sharps and flats).
