Fairly experienced guitarist and pianist here. No that does not sound good. It sounds less than bad but not good.
Spot on. I will never trust a musical review on fractal musical composition by anyone other than fairly experienced guitarists and/or pianists ever again.
Perhaps a school bell. But it would get annoying as fuck very quickly. Actually perhaps sticking it on repeat in a torture cell would be a good place for it. It’s not bad enough or good enough to be likeable.
One does not have to be composer to judge music. Also it is very subjective. In my opinion the piece is a short phrase that does not cause immediate allergic reaction. But it is not a composition.
Some math translated to notes and producing reasonable harmony is not really that exciting imo.
