A.6.1 Transcription of mensural music
When transcribing mensural music, an incipit at the beginning of the
piece is useful to indicate the original key and tempo. While today
musicians are used to bar lines in order to faster recognize rhythmic
patterns, bar lines were not yet invented during the period of mensural
music; in fact, the meter often changed after every few notes. As a
compromise, bar lines are often printed between the staves rather than
on the staves.

A.6.2 Gregorian transcription template
This example demonstrates how to do modern transcription of Gregorian
music. Gregorian music has no measure, no stems; it uses only half and
quarter note heads, and special marks, indicating rests of different
length.
