I cannot critique
I began multitasking as this song played and it just felt 'right'. I cannot correctly critique because it just became the background music to my life. For that, I thank you.
Wow... I feel like this is the calm after a storm, or something. This is an improvisation? You are a musical genius.
Even if it's only a faint idea, this sounds like it would be a complete piece. Simple is great in some instances, especially when it is pushed like this one is. Great job, and good luck with your portfolio!
You could consider it a full song since it ends on the tonic.
Please contact me if you would like to use this in a project. We can discuss the details.
