This is the sheet music for C-V Alkan's Marche Funebre, Op.26. It is based on F. Lucca's (~1847) source. However, I made a few edits as this was for my own pleasure that I list here for clarity:

1. I halved the tempo and all note durations for a better fit with the mood of the piece.
2. I changed key signature as appropriate whereas the source resolutely sticks with a single key signature despite clear and extended changes.
3. To reduce the number of pages and generally improve layout, for some measures I make use of a single stave for both hands. I find this perfectly easy to read (and superior to the source), but I concede it is not conventional.

Beyond this it is broadly fastidious in adhering to the source.

As a note, I wrote this using my own python library. I have put the url as the maintainer, but if this is not acceptable, please use my name (Thomas Morgan).

Edit to add: Because this was written first in python and then compiled by a machine into lilypond it fails to meet best practices. If you want I can include the python code, which is more nicely formatted. I may also be able to tweak the python library to better approximate best practices in its output. I don't really fancy manually editing the lilypond code to bring it in to line though!

Thanks,
Tom
