And we get some playable tunes. We might be able to improve the transposition
further by taking the Cello approach of calculating the minimum distance outside
the comfortable range. One for the future.
Jane says: Am most comfortable between the bottom G (the bottom line of the bass clef) and top D (the note above middle C), but can play from bottom C upwards (the C string is a bit growly) and at a push can get as high as the A above middle C.
Implement the following rule:
1. If range is G to d', transpose down 2 octaves.
2. If lowest note is < C, transpose down 1 octave.
3. Otherwise calculate the distance above d for the highest note on a one
octave transposition, and the distance below G on a two octave
transposition. Find the smallest, and use the corresponding
transposition.
1. Only show tune markers when a tune change is in the middle of a line.
2. Only show repeat starts |: if the repeat start is in the middle of a line.
3. Final bar end mark must be a thick line.
The official rules for a repeat are that if there is no left repeat
marker |: then the repeat starts at the previous double bar.
That way output where the colour isn't appropriate, such as Nook or the newly introduced
A4Lulu output (which is the A4 book but with white cover page and no end coloured page, and so
suitable for using as the content on Lulu, where the cover is separate) can omit the colour.
Use tabularx to put tune title, image and any following content into
a table. This should (a) get the following content closer to the tune image,
and (b) stop LaTeX splitting them over a page.
Currently we rely on any N: field with a Change: subnotice being the first
N: field. Add --contains field to abcfield.py to remove this restriction.
Also use it to extract new subfield Credit: and add that if present
to the tune information in print and on web.
Introduce vestigial copyright page and move instroduction before the contents,
so on A4 it appears on the verso to the content recto. Tunes then start double
page spread on the next page.
Add a \cleardoublepage before the index of first lines to force that to start on
a new double page. This minimises the page turning necessary to see all the index
lines.
This way the titles remains a constant size even if the image needs to be scaled.
And we have that text appearance under our control.
I can't find a way of switching off the tune title in abcm2ps, and have worked around
by setting the title format to Y0. Y is not a defined ABC header and is not found in
any Dottes tune.
Treat the tune title as a paragraph (ragged right). Set the column widths to give
a wider and hence larger first line tune graphic.
Keep using the cropped first line graphic, and introduce our own gaps between lines
to keep the tune separations clear. I did look at using the grpahics borders, but that
gives left and right margins too.
