"Western notation makes it easy to notate notes, rests and chords with durations like1/4
and3/16
. But notating notes, rests and chords with durations like1/3
can only be done with recourse to tuplets or ties. Abjad formalizes the difference between durations like1/4
and1/5
in the concept of assignability: a durationn/d
is assignable when and only when numeratorn
is of the form2**i-2**j
withi>j
and denominatord
is of the form2**v
. In this definitioni
must be a positive integer, andj
andv
must be nonnegative integers. Assignability is important because it explains why you can set the duration of any note, rest or chord to1/4
or7/4
but never to1/5
or7/5
."
Yes, I’m part of the Abjad family! As long as, I assume, the request is for a way to compose while thinking in clock-time the solution would be the abjad-ext-nauert
library (https://github.com/Abjad/abjad-ext-nauert). It is a quantization library based on Paul Nauert’s paper on Q-grids. The library was originally written by Josiah Oberholtzer and recently refactored by Tsz Kiu Pang after languishing for some time. I have never used the quantizer so I’m no help in that regard, however the documentation can be found here: https://abjad.github.io/api/abjadext/nauert/index.html
Hi Andrew,thank you for your answer. I’ll tell you a secret: almost the entire occidental notation system is a nice and juicy cartesian linear graph.Anyway, as you said, no notation program can do this task. As far as I know maybe just bach library inside max.The idea maybe could be transposed in another way: is it possible for each measure (e.g. quaver = 60) to write a lilypond score that take just some note and an x value for space free from tempo link?On 4 Feb 2023, at 10:32, Andrew Bernard <andrew.bernard@mailbox.org> wrote:My composer colleague always wants to write 3cm = 1 second for his scores. I insist that music is not linear graph paper and never was. So we disagree. I just do not believe musicians read music that way. Yet this is what some people want. Consequently I have looked into this and I do not know of any notation program that can do it. if you think about it, forcing a specific length for bars etc means the sophisticated layout engines cannot do their job.
If I am out of date and this _can+ be done, then I really want to know about it.

I’ve always wondered if it’s possible to write a lilypond score in absolute time, just giving almost 2 parameters: note and absolute time in seconds, without the measure boundaries.
