In other words, enums are a restricting layer on top of classes and class constants, intended to provide a way to define a closed set of possible values for a type.

The Doom melody requires more memory than others, so make sure your board can handle that amount. If not, you will usually encounter an error during compilation.

As a workaround, you can try removing some of the notes (along with their respective durations) to fit the melody on the board.
