If I had any idea how to read music I would be able to explain this but I can't so I will just have to take my 5 year olds word for it...
After spending just 1 minute at the chalkboard writing two lines of music she clapped her hands. With a ruler in hand as her pointer she announced,
"Alright class, this is easy. Just repeat after me. Run, run, walk, walk, rest, real long note. Got it?"
"One more time. Run, run, walk, walk, rest, real long note."
When Sam got home she did the same routine. His reaction was pure astonishment.
"Our kid is a genius."
