Do your students think that a whole rest always gets 4 beats? If so, they probably get confused when they are asked to add a rest for the entire measure in 3/4 time and not use dotted rests! According to the Oxford Concise Dictionary of Music, “The whole-note rest is used as a whole measure rest, irrespective of the actual time-value of the measure.”
I print out my NoteBoy posters on cardstock and laminate them. Then I place them on the sofa table in my studio for students to read and chuckle before their lesson. Humor has a way of sticking to your memory!
Teachers always ask me who is the note with the red cape and mask who always has a little comment to make. He is Mighty Dot, the super hero who wears black and flies to notes to make them longer. He’s a powerful guy. In my mind he has an accent kind of like Zorro, and he is an expert in rhythm and all things theory related!
If you are not familiar with my NoteBoy posters, check them out. There are NoteBoy posters on all kinds of music theory, such as lead sheet, ledger lines, and chord inversions, and they are all my gift to your music students. My students love them! Let me know if yours do, too!
