Oh…and one last thing…actually looking at things…you don’t even need new notes (eventhough I like Yorick’s notes for clarity’s sake).
Here’s why…
If you write 5/5, then the only mental things that shift are the following:
A whole note now equals 5 “quarter” notes instead of 4.
A half note now equals 2 “quarter” notes and an “eighth” note.
Whatever tempo is listed, it’s actually played roughly 31% faster.
Everything else stays the same.
Why?
Because you are playing 31% faster, which automatically causes the 5th to take place.
When you see, 4/5 as the timing signature, you know that instead of 76bpm listed, you play this at 100bpm and hold the whole notes for 5 quarters and the half for 2 quarters and an eighth.
Which means when you write down a whole note, it will carry for one and a quarter measure.
When you write a half note it will carry for 2 quarters and an eighth of the measure.
So you can’t place a half note and two quarters in 4/5 timing.
You can place a half note, a quarter note, and an eighth note and keep in mind that it will travel at 100bpm instead of 76bpm.
It’s all so terribly simple when looked at this way.
And it doesn’t take any funky conversion for every note in the system…only the whole, the half, and the tempo.
Man…this is better than I had expected!
(edit…now the only thing that’s needed is a notation like a dot, but that represents a quarter of a note’s value added to the notes value…otherwise you end up writing whole+quarter with a tie, and half note + eighth with a tie…unfortunately, there isn’t a notation for doing this…yet)
(edit#2…staccato a dot but not the note? lol…boy…I’m sure that would confuse the heck of people, lol)
