What is 8va?

I know! I know! !Yo se! !Yo se!

8va means "octave," and when you see it on sheet music, you play up an octave or down an octave for the notes indicated under its bracket.
 
I think they're short for ottava alto and ottava basso, respectively, but 8va can also (confusingly) mean octave lower when written below the staff. An octave lower marking isn't something I'd expect to see on bass music. Also, a little eight connected to the top or the bottom of the clef has the same meaning. Almost all bass and guitar music really should have it, since we play an octave lower than written.
 
Thank you. I was trying so hard to remember what that was, and it's been so long since anyone wanted something played down an octave on sheet music that I drew a blank.

Actually, correct me if I am wrong, but isn't all sheet music written for bass guitar technically an octave up? Most people just don't write the 8va, it is assumed.
 
From sounding pitch, yes. But within the context of a chart, you'd write 8va/8vb. You don't need to write 8vb for a whole chart, and in fact shouldn't. Bass is considered a transposing instrument.

That's a slightly confusing (to me) way to put it. It's all written "8va", you might say, but the proper marking to put there would be 8vb (or a little 8 dangling from the clef), to tell players to take it down an octave to the proper pitches.

Writing "8va" or "8vb" is totally different to the little 8 dangling from the clef. The first ones are octave transposition marks which tell the player that he/she should play not the written notes, but an octave above or below, depending on the mark. The 8 below the clef is just a reminder about the fact that every note written in that staff is actually sounding one octave lower (which is the case for guitar, bass guitar and double bass). The player shouldn't play any different than he/she understands by direct reading. BTW (I think this has been said in a previous post) guitar, bass guitar and double bass should have the little 8 below the clef. I don't know why it is not used (maybe it is, but don't remember having seen it before). The only case I've seen it used (and very strictly) is in tenor (voice) sheets, which are mostly in treble clef, but the male voice sounds one octave lower than written in this clef.
