--Big Grin--. I'm not expecting the group to choose this song, I really put the score up hoping it might answer your question regarding rhythm of the song.
Finale is a notation software. I use it to prepare paper copies of a song for practice work and to hear what it sounds like. I bought a copy of their "Song Writer" version for my daughter some 10-12 years ago. When I decided to try to learn music, they let me upgrade to the current version for a small amount, and later offered an enticing discount to upgrade to the full 2014 version and I bit. It is mostly overkill for my needs. I used TablEdit TAB notation software but switched to Song Writer to work on learning to read standard notation.
I believe you can write any style of music notation with Finale. Eighth or sixteenth notes are easy to write, as are triplets. In playback (transport) mode, it will play machine or human style, and can interpret the notation in swing triplets. I have to verify that it can do shuffle, which I understand to be a long swing style. It will apply human playback styles including funk, jazz, Latin, pop, reggae, rock, samba and various classical music styles, and you can build custom styles if you know what you are doing. Me, not so much, but I'm learning in bits and pieces.
This is not a studio mix, more like a midi product. I know little of mixing yet, so I'm guessing that midi files or audio files (wav or MP3) files could be exported to a DAW for mixing. Had not thought that far yet.
The tempo should come up for any production and I should have increased the tempo, but forgot and sent a practice tempo. I'm still trying to learn the piece and it is too fast for my beginner fingers. I play it on a tenor ukulele, but had to put it aside for a bit as I improve my fingering. Definitely a novice attempt.
