Two handed tapping

I think I might have been making some mistakes for the last few years. Because of Total Guitar (pffft!) I believed two-handed tapping involved tapping a note with the right hand then using a hammer/pulloff technique to play 2 more notes with the left. Because of this, when ever someone said 'can you two-handed tap?' I'd just play them some Eruption or something and sit there looking smug. However, something that was mentioned before about tapping made me wonder;
am I wrong? Are tapping and two-handed tapping something different?

i dont think so

As far as I know...two handed tapping would be like hammering on some notes with both hands consecutively. For instance...u could play a chromatic type thing so one hand would play like 5,6,7,8 on the high e string and ur other hand could play 9,10,11,12 right after that. Thus using all 4 four fingers on both hands. Jennifer Batten did a crazy two handed tapping version of Nicolai Rimsky-Korsakov's Flight of the bumblebee utilizing two handed tapping in this chromatic fashion. That's what I've always thought two handed tapping was. Hope that helps.

kinda like 'day at the beach' by satch then?

Umm...day at the beach by satch? I've never heard that song sorry. I know Satch does it on "Bamboo" off his last album and I think he does it on a song called "Midnight"...i suck at remembering song titles tho. I know for a fact tho that he does it on bamboo because i've seen him play it and I'm listening to it now. Satch does a bit of two handed tapping...especially live.
