There's a very useful fingerboard map that goes on your right on your fingerboard. No sticky stuff involved. I found it useful because it's color coded and comes with color coded music that's designed to help you learn how to read music. Note names are included on both the map and the sheet music. Really works, and isn't expensive. You can see it at FretlessFingerGuides.com. Hope this helps.
Dana:You are right - those violin guides are really neat! Thanks for the tip.
The best duet Christmas songs are those ones you knew & loved as a child! This set of 14 "a capella" carols arranged for 2 voices is just right for caroling!
This sparkling piano arrangement of the main musical theme from The Snowman will win your students' hearts and imaginations, too, with its soaring beauty!
