1. The note must be a particularly notable example of how the note should be delivered. This one is intuitive, but I suppose I'll put it in nonetheless.
2. No "singer-spamming" allowed: no need to post five examples of Geddy Lee hitting F5's here, not every one deserves to be included and not every one will be. Just use common sense when posting clips from singers here.
3. While it's not required, it would certainly help if the note in question was particularly well-known and had developed some sort of reputation for itself.
4. PROVIDE LINKS. That way we can determine if they are indeed of requisite quality and worthy of thread inclusion, and we can also link to them in the thread itself. Also PLEASE FORMAT THEM LIKE THEY ARE IN THIS POST. It makes my job much easier.
Amazing F5 from Martha Wash in "It's Rainin' Men". youtu.be/l5aZJBLAu1E?t=2m46s Also a more buried whistle F6 from Martha at the end of the same song, though the fade out in the original mix kills it a bit. It's more audible in her range video. youtu.be/0pRte_fLTWw?t=6m12s Despite being known largely as a one-hit wonder, both Weather Girls had amazing voices.
