                                       Ligatures
                                          Apel, Willi (1961). The Notation of Polyphonic Music, 900–1600
                                                                                       L = Long
Rule of Thumb: Don't change syllables on a ligature.                                   B = Breve
                                                                                       S = Semibreve
                       Punctis Augmentionis
                                        Only in Imperfect Mensurations
                                        Dots act like in Modern Notation:
                                        Adds one half the length of the note
If Imperfect Mensuration, this would
have the value of 3 Crotchets
                                                        Imperfection                                                     4
                        In Tempus Perfectum, Breves are by default worth 3 Semibreves
                         In Tempus Perfectum, Breves are Sometimes worth 2 Semibreves
                                   In the following examples, the modern notation has been halved for clarity.
                                                     =          =        =
                                                 Tempus Perfectum Prolatio Minor
If a Breve is followed by a note or rest that has a length of a Breve or greater, the Breve is Perfect—worth 3 Semibreves.
If a Breve is followed by 3 Semibreves, the Breve is Perfect.
If a Breve is followed by a group of smaller notes that equal 3 Semibreves, the Breve is Perfect.
If a Breve is followed by 2 Semibreves, the Breve is Perfect.
(The second Semibreve turns into an Imperfect Breve. This will be explained later.)
If a Breve is followed by 1 Semibreve, the Breve is Imperfect—worth 2 Semibreves
If a Breve is followed by 1 Semibreve worth of notes, the Breve is Imperfect—worth 2 Semibreves
If a Breve is followed by more than three Semibreves, the Breve is Imperfect.
If a Breve is preceded by 1 Semibreve, the Breve is Imperfect
If a Breve is preceded by more than three Semibreves, the Breve is Imperfect.
If a Breve is preceded by and followed by a Semibreve, the Semibreve following the Breve does the Imperfecting.
Rests cannot be Imperfected.
Rests can Imperfect Breves.                                                           These are Guidelines.
                                                                                      They are not hard and fast rules.
                                          Imperfection                                                            5
                                  Tempus Perfectus Prolatio Major
                                Tempus ImPerfectum Prolation Major
Minims can Imperfect Semibreves.
Minims can Imperfect Breves and Longas. This is called Partial Imperfection.
                                                                     General Assumtion: 2 Breves to a Longa.
This leads to weird combinations, especially in Tempus Perfectus Prolatio Major.
For example, you can get recursive Imperfection
The weird stuff doesn't happen often in actual music, but it's written about at length in music treatises.
                                              Alteration
Alteration occurs when there are two Semibreves following a Breve.
The second Semibreve turns into an Imperfected Breve.
                                    Punctis Divisionis
In Perfect Mensurations (Everything Except Tempus Imperfectus Prolation Minor), a dot after a note can indicate
that the rules of imperfection are to done differently than expected.
For Example:
                           By default indicates
                                 indicates
The Dot indicates that the Semibreve before the dot Imperfects the Breve before the dot.
The two Semibreves form the alteration discussed above, thus the second Semibreve becomes an Imperfect Breve.
                                                                                                            6
               What's Not Covered In This Handout
                   Sometimes in music written in white notation some of the notes are colored
Coloration         black or red. This is a way of changing the meter mid-piece. To find out more,
                   check the Recommended Reading.
                   Sometimes there will be numbers or fractions written in the music. This is
Proportions        another way to alter the meter mid-piece. To find out more, check the
                   Recommended Reading.
                    Often there will be notes in the music that need to be altered even though no
Musica Ficta        accidentals are written in the music. A general rule of thumb is if there's a tritone
                    between the cantus firmus (usually bottom line with lots of long notes) and an
                    upper line, alter the upper line note to fix it. OK alterations: B – Bf; F-Fs; E-Ef;
                    C-Cs. There's a bit more to it than this, but this will get you pretty far.
