Question for Pete Dunk about the Northern Roots Tunebook
« on: December 07, 2019, 01:19:26 AM »

Northern Roots Tunebook

Thanks for posting this, Pete. Looks interesting, I'll have to have a look through some of these tunes.

[I'm posting this as a new topic in the ABC sub-forum because it's an ABC question; Pete's original post is in the Tunes parent forum)

For now, I just have an ABC question, maybe you can explain...

I noticed that in these tunes, the time signature gets repeated on every line. That looked a bit odd to me, and I wondered why it was happening.

I couldn't see any obvious reason, so I hacked one of the tunes and chopped stuff out until the repeated time signatures went away.

I found it was the use of two voices ("V1 gchord=down" and "V2") which seems to trigger this behaviour.

But why are two voices needed in the first place, and why does having them cause the time signatures to repeat? I'm mystified.

(I'm looking at the first tune, and I'm using ABCExplorer. But your PDF also shows the repeating time signatures, so it's not just something specific to my setup. And it does seem apply to lots of the other tunes as well, not just the first one)

If you could explain to me what's going on, I'd be very grateful!

Cheers, John

Well now, I can explain why I use the the two V: fields but not the side effect of the time signature appearing on every line of music, although I do have an observation.

Let's deal with the V: fields first. After a lifetime of reading chord symbols and little fretboard windows printed above each line of music (40 years playing guitar) I've grown used to the alternative style which seems to be the standard for 'accordion music', putting the chords below the stave and now I actually prefer it. To make this happen the header V:1 gchord=down is required. On its' own, this isn't good enough for Explorer (I use Explorer exclusively as my editor) which complains that the statement is illogical as there is only one V: field, adding a blank V:2 line satisfies the software. Every now and again (by no means always) pressing play to listen to the tune results in the play bar at the top scrolling frantically and no sound output, this puzzles me mightily and I have no idea why it is intermittent. The remedy is simple, after the K: field (end of headers, now everything is part of the body text) add V:1 to trigger the V:1 gchord=down statement:

M:4/4
L:1/8
%%titlefont Helvetica 22
%%subtitlefont Helvetica 16
%%composerfont Helvetica
%%partsfont Arial 20
%%partsbox
%%gchordfont Arial 16
%%barnumbers 1
%%MIDI program 73 % flute
%%MIDI chordprog 1 % piano
V:1 gchord=down
V:2
Q:1/4=160
K:D
V:1
P:A
|:FG|"D"A2A2 A2Bc|etc

Deleting the three V: statements gets rid of the extra time sigs (which also appear on the PDF output) and prints the chords above the stave in the 'normal' manner. My observation about this printing of the time signature on every line is that it appears to be an ABC Explorer 'quirk', this doesn't happen in Easy ABC. When things like this happen I tend to just live with it because I have no explantion and it appears to be software specific, not very satisfying I know, but there it is.

OK, that makes sense. Thank you very much for the detailed explanation.
