Which song are you comparing it to, please?
not really comparing to a song. when you think of clarinet, you think of dixie land and big band of course. it’s also a plaintive accent instrument for orchestra.
somehow the clarinet doesn’t seem to work as well as the main voice here. maybe i’m biased to the standard use in arranging for emphasis and ornamentation. i guess think the keyboard should have been the main melodic line. think you need a guitar or something for rhythm support with the drums.
hope that clarifies what i was thinking as i was listening...
