Ancient and modern from one source
Using tags to produce mensural and modern music from the same source
Using tags, it is possible to produce both mensural and modern notation
from the same music. In this snippet, a function \menrest
is
introduced, allowing mensural rests to be pitched as in the original,
but with modern rests in the standard staff position. Tags can also be
used where other differences are needed: for example using “whole
measure rests” (R1
, R\breve
, etc.) in modern music, but
normal rests (r1
, r\breve
, etc.) in the mensural
version. Converting mensural music to its modern equivalent is usually
referred to as transcription.
