Grandchild #3, 2 years, 2 months, pushed beyond his limited speech with rhythm dialogue. While in the car, Grammy established duple meter with the inflection of a question, awaiting his musical answer. He responded excitedly with, “Again!” Grammy accommodated with a different pattern, getting his enthusiastic, “Again,” through repeated turns. He then began responding with a short rhythm pattern on “bah,” after which each rhythmic response became longer and more precise.
