Musical notes

In this blog post we are asked to find out the ratio the Frequency goes up each note, to do so you have to divid the past frequency by the current one.

  1. Hmm, looks like this isn't quite finished - you didn't answer the questions. Plus, I think you may have calculated the ratio in the wrong "direction" - if it's growing, the ratio should be greater than 1.
