A new student of mine brought some music in that she needs to learn for school. I don't have much experience with jazz music, and some of these symbols are pretty new for me.I'm not sure if I can explain these well, but here goes:- instead of a group of notes being played at the same time, it looks like a line on an angle with a stem. (Some of them don't have stems too.) (I can scan these and send them to someone if they know anything about jazz music.)- In an empty bar, instead of a whole rest, I see something that looks like a diagonal line with a dot on top and a dot underneath.- The next symbol is a diagonal (almost horizontal) line with a line at the left side going vertically and a line at the right side going vertically. On top there is a 3 written. The only thing I can think of this is that there is to be nothing played for 3 full bars.Anyway, I would appreciate any help on this!Thanks,D
