I am creating a lengthy score (using \bookpart) which contains a mixture of chant and polyphony. If I use \include “gregorian.ly” it distorts the polyphony, but without it I cannot set the chant the way I want.
Is there a way to confine the \include “gregorian.ly” to just the chant sections? I’ve tried various options but always get an error message unless it’s placed at the top of the file. Thanks.
