It is possible in free-notes.net to switch between different collections. If you use "Practise!" or "All pieces", you see only the pieces of the currently selected collection.
As long as you do not select a collection, you get the preselected first collection ("the main collection ...,", see below).
What did I change?
The most frequent problem is the length of measures. When you have a repetition, the upbeat plus the repeated part
of the last measure should rather have a complete measure length. If this is not the case, you have a break in rhythm.
It seems, as if formerly this was seen rather relaxed. I have tried to fix this with only minor changes.
Another problem are the accidentials in the measures. Unfortunately I do not know, how long they were
regarded as valid. Sometimes I have the impression, they should be valid only for this note, and sometimes, as if
they should be valid, until there is a contradicting accidential. I have adapted it to today's convention, that
they are valid for the measure in which they occur. And here I have sometimes decided according to my personal taste.
Sometimes I have changed the key without changing the notes.
In very rare cases I also have changed a note, when the note range would have been too big.
What did I not change?
The biggest remaining problem is the following:
There are several pieces with two repetitions following each other.
And here the second repetition has an upbeat different than the upbeat of the first.
Normally this is not possible. But as it is so in the original and I do not know a clean
solution, I left it as it was. I imagine both parts as somehow separate, with a kind of break between them.
At least I added a markup (like 'P:2') at these spots.
There are also some pieces, that I did not understand at all. They are unchanged.
