Chord chart editor

Chord chart is a form of music notation which only specifies harmonies, rhythms, and some structure information(rehearsal marks, repeats etc...), which is used mainly among session musicians (popular, jazz etc...).  Fumenbook is a tool for creating and storing and viewing chord charts.

- You can create chord chart using the "fumen" markup language (https://hbjpn.github.io/fumen/) for chord chart or using GUI. The markup language of "fumen" is very intuitive and easy to write. You can write chord chart much faster than to write with GUI once you get used to the grammar.a

- Scores are saved in the cloud. You can edit and view from either mobile app or web browser clients.

- Mobile application can be used even when the internet is offline or unstable. This is useful when you are in the place where internet connection is not available or poor such as live bar at the basement.

- Basic features like score, setlist searching, character size change, key transposing.

- Set of your scores can be grouped as setlist, which is useful for live performances.

- Rendering is as per "fumen" rendering engine.
