About Chord Name

You can change chord name to any text. Piano Kit is flexible. However, the idea that follow Chord NOTE style is useful.
It is very simple.

For example, you type “GM7/B [IV]”.
This resolve into Root (first 1 or 2 characters), Chord Name (Chord Symbol), Bass (after slash), Comment (after space & [).
In this case, Root : G , Chord Symbol : M7 , Bass : B , Comment : IV.

  1. Lowercase and uppercase are different text. For example, M is major, m is minor.
  2. You cannot omit “(” and “)”. These have an important meaning in chord name.
  3. You don’t have to worry about space character without comment symbol ” [“. (space and square brackets)

Yes, it’s almost same as music theory. The only special practice is the 3) comment symbol.

By the way, because of the ease of input name, respectively sharp and flat, Chord NOTE use # (Shift-3) and b (Small B).

If you use this Chord NOTE style, you can use it to search on Chord NOTE, Guitar Kit and Piano Kit without any modifications.
