Without going into too much detail as to the why's and wherefore's of the question (I'll put it at the bottom, question first), I am curious about the copyright laws regarding whistling copyrighted music in a youtube video. It wouldn't be the focus of the video, but it would be a passing part of the video. I'm wondering about the ability to monetize such content.
As for why I'm curious about this, I've recently been thinking about starting a youtube channel. I have no delusions of grandeur, and I don't want to be presumptuous, but it serves to be prepared. I tend to whistle, and without trying to sound cocky, I'm quite good at whistling music. The channel would be man-cave workshop type content, among other things, and I would like to include bits where you can hear me whistling or singing along with the music that I'm listening to (the video music would be non-copyrighted, but I would quiet it to hear the whistling or singing). It would be short snippets, no more than 5 or 10 seconds, and you wouldn't hear the music that I'm hearing because I use headphones. If I ever got to a point where I could monetize my channel, would this prevent me from doing that?
