I have been viewing some videos on Youtube of tremolo done fingerpicked (flamenco style and such), but am confused. Is it a rapid, repeated hammer-on after the note is picked once? Or is it picking the note very quickly? I'm just trying to figure out exactly how to do it, like with this for example (from a blues instructional book):

``````------------------------------------------
---3---------------------------------------
-----2^0----tr---------------------------------
----------2-0^2-------------------------------
------------------------------------------
------------------------------------------``````

What would I do on the 0^2tr ?? TIA
Well, assuming that ^ means hammer-on (although I usually take it to mean bend, but that makes no sense here) that looks like a trill rather than a tremolo to me. Which would just be a rapid succession of hammer-ons, yes. I could be wrong.
That's not "tremolo" that's a trill, a repeated hammer-on/pull-off between two notes.

a trill is rapidly hammering on and pulling off, tremolo is rapidly picking a note.
Ah yes, I'm such a clown, I just rechecked the book and it indeed it's tr which is trill, sorry. However, what would tremolo be on one note? Still confused on that

EDIT: Thanks burnthestars So just really quickly picking one note?

Tremolo PICKING is rapidly picking one note.

Tremolo is similar to vibrato.

Yes, in electric guitar terms tremolo picking is just picking one note as fast as you can.
