I`mn trying out for all county band and in my music, there`s this s flipped over on it`s side. What does it mean?

Does it have dots each side of it?

May be a "turn" or "inverted turn". Look at http://gc-music.com/Ornament.htm to see if that`s it, and how to play.

It`s called a D.S. Al Coda. The words direct you the symbol, which directs you to "To Coda", then that directs you to a seperated piece of staff with a thing that looks like crosshairs.

Thanks for the site, but what does it mean? How do I play it..... ect.

You mean the mordent? Well, you start on the note listed, go up one note, then return to it again. EX: you are given a C with a mordent followed by your other notes; you play CDC and then your other notes

Oh yeah,if this is over a quarter note, these three notes will be played as: two 32 notes tied to a dotted eighth.
CDC--
1 e+a
