I would like to map a set of buttons to the note numbers
that correspond to a specified key. In order to do that,
I would need to know what the root note is and if it is
major or minor. If I had some interval table I could
then map those notes to my buttons. Does anyone have a
table that specifies the major/minor interval values for
all keys? A table of modal interval values would be great
to have as well.
