If the ]2 is just multiplied to the length of the notes inside the chord, there would be no benefit of the [..]2 notation. You can write better the same way you did: [d12z4] I meant that each note *in* the chord has the length as specified there and the length after the ] doesn't change that. The length after the ] gives the time when the *next* note after the chord starts. So with M:4/4 and L:1/4 [A4C4E4]2 a/4a/4a/4a/4a/4a/4a/4a/4 means play the AMinor for 4 beats but on the 3rd beat start a tremolo on the note a until the end of the bar. You can not write this with any of the discussed chord-length-rules because each note in the chord has length 4. Of course you can whrite the same as [z2A4C4E4] a/4a/4a/4a/4a/4a/4a/4a/4 suppossed the the chord-length is taken from the 1st note and rests in chords are allowed. Which one is more readable or easier to maintain is a matter of taste. But just now came in my mind: what if you could write this [A4E4C2]0 ab[C,2]0c'd' Supposed the length zero is allowed, this whould mean start A4 E4 C2 on beat one change the C to a C, one beat three. And on top play a melody abc'd' for the whole bar. Ok, take this as a joke. But why not allow the syntax. It's consistent whith the single note length modifier so it seems to me its easy to understand. There are no ambiguities in what it means so any software can easy figure out what to print or to play.

If the ]2 is just multiplied to the length of the notes inside the chord, there would be no benefit of the [..]2 notation. There is a considerable benefit: brevity. If you've written many melodybass pieces, you'll have done a helluva lot of [G,,8B,,8D,8] stuff that would have been more readably written [G,,B,,D,]8 . We have had several postings in this list over the years from people who've tried to do that and been surprised to find it didn't work. It's so intuitively sensible that it *ought* to work. I meant that each note *in* the chord has the length as specified there and the length after the ] doesn't change that. The length after the ] gives the time when the *next* note after the chord starts. So with M:4/4 and L:1/4 [A4C4E4]2 a/4a/4a/4a/4a/4a/4a/4a/4 means play the AMinor for 4 beats but on the 3rd beat start a tremolo on the note a until the end of the bar. You can not write this with any of the discussed chord-length-rules because each note in the chord has length 4. Using my absorptive-tie scheme: [A2--C2--E2--] [a//A//--C//--E//--][a//A//--C//--E//--][a//A//--C//--E//--][a//A//--C//--E//--]\ [a//A//--C//--E//--][a//A//--C//--E//--][a//A//--C//--E//--][a//A//C//E//] It's about the worst possible case for that, but it can represent it. Macros would make it more readable, but this is an obvious case where using separate voices is the way to go. Of course you can whrite the same as [z2A4C4E4] a/4a/4a/4a/4a/4a/4a/4a/4 suppossed the the chord-length is taken from the 1st note and rests in chords are allowed. That's completely counterintuitive - a rest that doesn't get either played or displayed and is just there to control the playing and display of other notes? But why not allow the syntax. It's consistent whith the single note length modifier so it seems to me its easy to understand. There are no ambiguities in what it means so any software can easy figure out what to print or to play. Software might manage it but I can't see many humans doing so. === http://www.purr.demon.co.uk/jack/ === To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html

John answered for me ... John Chambers wrote: Well, I can think of a simple example of how one might use this: [A4G2E2]2[F2D2] This would have a 4-count melody note above the [G2E2][F2D2] chord change. With L:1/8, the first chord could be drawn on a single stem, with an open oval for the A4 note and filled ovals for the G2 and E2 notes. This sort of notation isn't at all unusual in keyboard music. The abc seems quite readable to me. That's exactly what I meant. Starling wrote: It could be too flexible though. How is [A4G2E2]3[F2D2] supposed to be interpreted? :-) play A4,G2 and E2 on beat one hold it for 4,2 and 2 beats. than start playing F2 and D2 on the 4rd beat (after a z3) and hold it for two beats. An accordion surly can do that, but if you should write it down this way ? Of course this syntax gives much freedom to write nonsens. But this is not the point. The syntax should provide a way to write something meaningful in a readable form. It is for the software to find out the meaning or to complain if it doesn't understand. But I don't think that you can define a syntax that prevents you from writing nonsens. Bryan Creer wrote: I'm afraid I got rather lost by your named nesting idea as well. John Chambers wrote: Me too.
