Re: mesures d'égale longueur |

Bonjour,
Je pense qu'il est possible d'écrire une grille d'accord assez facilement,
avec peu d'ajustements manuels.
Il faut que les mesures soient effectivement d'égales longueurs.
Un changement de chiffrage doit être possible.
On doit pouvoir écrire une mesure de 1° fois et une mesure de 2° fois.
On doit pouvoir choisir le nombre de mesures par ligne.
On doit pouvoir indiquer le rythme souhaité.
On doit pouvoir diviser les mesures en 2, 3, 4...
ça doit être facile à réaliser.
Voir ici:
http://lilybin.com/2yg9pw/1
Su cet exemple, il y a une seule correction manuelle au niveau de la 3°
ligne, à cause du rythme, mais pas de correction manuelle au niveau de la
division des mesures.
Voici une grille vierge:
http://lilybin.com/l4044v/1
Pour diviser les mesures, il faut utiliser les commande \/, \X, \Y, \RV,
\VR.
Avec ces commandes, les accords sont placées de manière automatique.
La commande \/ attend 2 accords.
\X attend 4 accords
\Y et \T attendent 3 accords
\RV et \VR attendent 3 accords.
Les chiffrages de mesures perturbent la longueur des mesures, il faut les
indiquer dans un markup comme dans mon exemple ici:
http://lilybin.com/2yg9pw/1
Les barres de reprise perturbent légèrement la longeur des mesures, mais ça
passe.
