Notation Question

[steve jones]

In a Beethoven sonata, what does 'tr' instruct the performer to do?

Obviously it refers to a trill, but in the piece Im learning there is nothing other than the 'tr' symbol. Does Beethoven intend anything specific with this symbol, or does it just mean trill away without regard for rhythmic accuracy?

The piece is Op49 No2, the old beginner sonata. I want to learn this before I try anything more challenging, mainly to familiarise myself roughly with the big mans notation, techniques etc. Right now I am just playing a triplet trill before the grace notes, but Im not sure if that is whats intended. I have a couple of records but they arent good enough to pick out the exact architecture of the trill.

Thanks guys!
