So, I have this song on sheet music for the flute, and what does this mean!? There's this part where have to hold the F for 4 beats, then the next note is a B!. But, on top of these 2, there's this curved line that means you have to slur the F and B, and sure, I can do that, but then, right beside the slur line, right to the left of the slur line, right next to it, it says tr!. I know tr means trill, but isn't the symbol for a trill supposed to be tr, and then the thick sqiggly line!? It's not supposed to have the slur line! What is this!? Is it now a gliss!? I don't get it!Www@QuestionHome@Com
