Hi SayDoo,
I think that while the material on both tracks sounded fine at first, thereafter, there wasn’t enough variety to keep the ear interested.
Before having a bash at writing stock music myself - by the way, I still haven’t had any tracks accepted - I went right back to basics.
Over 20 years ago I did a music degree and learnt virtually nothing of any value about writing music for the real world. The course mainly focused on a lot of way-out, avant-garde stuff that was so awful it would have your cat looking for another home. We had one lecture in three years on western tonal harmony.
Anyway, I know you didn’t ask for a bio, so I’ll get to the point.
About a year ago, I stumbled on a couple of books by a fella called Jonathan Peters, “Music Composition 1” and “Music Composition 2”.
Peters stresses throughout the two books that the most important principle of composition is “unity and variety” - you know, inversion, transposed inversion and that sort of thing - and he gives numerous examples to drive home the point.
Neither of your pieces, while sounding very professionally mixed to my amateur ears - had much in the way of variety, at least not up to the point where my ears wanted something different and I hit the pause button.
You’re obviously not some complete beginner, so I don’t want to cause offense by implying that you don’t know what you’re doing. Nevertheless, I do think that both tracks suffer from doing too much of the same for too long.
Disclaimer: I am not related to Jonathan Peters, nor do I have any connection with him whatsoever other than owning those books I referred to, which are priceless little gems.
