Can I copyright a sound effect? A sample? Or two notes?

Thats what i was on about, the sample rule. I thought it was 10secs.

To copyright a song very well could be one somewhere that I’m not aware of.

To trademark at sample, I don’t think there could be. The two second clips in the original post are examples of actual trademarked audio.

Same question here…Do you happen to know a source? I there was precedent that had determined that the length of sampled content, in and of itself, was not a litmus measure when evaluating a matter of substantial likeness.
