Slapping two strings

[iwannalearnbass]

I am working my way through Oppenheim's Slap It and am wondering how exactly you are supposed to play the two-note "chords". The only way I can get a good tone from slapping both of them is lower my right hand so that my thumb is more or less pointing at the ceiling when I hit the strings (D and G), but I'm not sure this is what I'm meant to be doing.

I'm thinking it could be more a strumming rather than slap motion?

Yep, I slap two strings at a time to play chords. My thumb points down though. I've seen it done both ways.

Honestly you're doing it right, how it feels natural.
I more or less do it the same way you do, try the strumming part, there is not right or wrong IMHO.

Just reorder that book (lost in a move )

Victor has a good how-to slap two strings on youtube.

The first half of page 15 from Mr. Oppenheim's awesome book has some great exercises for practicing both fluidity on 16th-note patterns and slapping double-stops. I don't use strumming for that. I slap both D and G string with my thumb using a downward motion.

EDIT: I'm referring to the old edition, without the tablature.
