This is in the BG section, and almost by definition the genres of music inhabited by Bass Guitar are non-classical. In my view, whether you're talking about Jazz, Rock, Funk, Pop or any of the more contemporary styles of music that use BG the number one rule in the rule book is that rules are made to be broken...it's only rock n roll but I like it
PS: I don't think I ever saw anything in Mel Bay about tapping, and you're definitely not supposed to strike the string with the side of your thumb or hook your finger under the string and let it snap back down, while we're at it, your not supposed to make the strings clack on the fretboard either but fortunately for us some unruly souls who came before us had the exuberance to ignore their instructors - although personally I wish that nobody had invented slap.
