Transcribed here is the the legendary Hendrix performance of The Star Spangled Banner. I’ve omitted the whammy bar dives mid way through the song that recreate the sounds of bombs or fireworks (or what ever you interpret them to be). Enjoy!
On the bend on the 7th fret your bending the note up on the 7th fret. Then without releasing the bend, you strike the note on the 7th fret and the let the bend down. The 7 in parenthesis (7) is just showing you the bend comes down. Then you pick the note on the 5th fret, hammer-on to the 7th, and pull off back to the 5th.
