Rick Beato did a video about being able to identify guitarists by a single note. David Gilmour was by far the easiest to recognize. It got me wondering how much work would it take to even be able to play a single note as well as David Gilmour. And even then I would still only be imitating someone, not creating something original.
Wow, true. The David Gilmour note is plain as day. Only other one nearly as easy for me was EVH. The Jimi note sounded like Jimi but like the top comment says, a lot of the others sounded like Jimi too.
Jimi and Eddie are the two singularities of guitar, though. Before them it was unimaginable for anyone to sound like that. After them it was the normal.
(Although they're also tones that a lot of players still try to chase for their entire lives and never really reach. There's some magic to them beyond the more obvious steps.)
I've heard two people separately tell me that Yo Yo Ma would start his concert by playing a single long, low note. And they both told me they were immediately hooked.
