Random Tip: Corda 2 Encore Level 7

The biggest difference between the 5-requirement orchestra pieces and the 7-requirements pieces is that you have to investigate something called a rachette (ラチェット). Once you get enough information about it, I believe it appears in the store and you can buy it. You can get information from some of the main characters as well as either 内田守夫 or 安西多恵子. Once you hear this information, talk to Kanezawa-sensei and he’ll tell you more, and then I believe you can buy it after that.
