Mathematics provides an important way to inform and interpret music. For example, because of a mathematical breakthrough (better ways to calculate the twelfth root of 2), Johann Sebastian Bach was able to write in every key. This set of problems is intended to facilitate interdisciplinary connections and reasoning with music. Math by the Month features collections of short activities focused on a monthly theme. These articles aim for an inquiry or problem-solving orientation that includes four activities each for grade bands K–2, 3–4, and 5–6.
