A great bulletin board for fall that uses all of those laminated leaves that you try to reuse every year.  (Come on!  You remember cutting them out for hours and now that they are laminated...you're gonna use them forever!)  Add a staff and a note on each leave.  Draw a bare tree (or purchase one from the teacher store) and an owl.  I would recommend printing the owl from a desktop publishing program.  The title "WHOOO Knows the Pitch Names?" completes the board.
