The basics : learning to see a neume

Before opening the Graduale Triplex, let us set up a few simple landmarks. By the end of this page you will recognise the Gregorian staff, its clef, and about a dozen fundamental neumes.

1. The four-line staff

Our modern staff has five lines. Gregorian chant, by contrast, is written on a staff of only four lines (the tetragram). That is enough, because Gregorian melodies move within a fairly narrow range. As today, the higher a sign sits on the staff, the higher the sound ; the lower it sits, the lower the sound. One peculiarity worth knowing : the clef can sit on different lines — it is not fixed once and for all as in modern music, and it sometimes even changes in the middle of a piece.

Definition — The clef

A clef is a marker placed at the start of a line that names one of the lines. In chant, two clefs are mainly used : the C clef (do) C clef and the F clef F clef. They do not fix an absolute pitch (the choir adjusts the pitch to its voices), but they show where the semitones fall, which is enough to sing in tune.

2. The basic note : the punctum

In square notation the commonest single note is the punctum — literally a « dot », drawn as a small square. A variant, the virga (« rod »), is a square extended by a small stem ; it often notes a higher note. When reading, punctum and virga are both worth a single note.

Graduale Triplex A punctum: a single square note, here on '-tus' of 'natus', Graduale Triplex p. 47 Square notation Punctum, square notation (University of Basel) Modern transcription tus Punctum 1 note — "na-tus", p. 47
Graduale Triplex A virga: a square note with a stem, marked with an arrow, here on '-le-' of 'Alleluia', Graduale Triplex p. 199 Square notation Virga, square notation (University of Basel) Modern transcription le- Virga 1 note (often high) — "Al-le-luia", p. 199

3. Two-note neumes

Things get more complex — and more interesting — when several sounds are sung on a single syllable. They are then grouped into a single drawing. The golden rule for reading : a neume is read from bottom to top and from left to right, following the stroke.

Graduale Triplex A pes: two notes joined vertically, ascending, here on 'da-', Graduale Triplex p. 47 Square notation Pes, square notation (University of Basel) Modern transcription da- Pes (podatus) 2 notes going up — "da-tus", p. 47
Graduale Triplex A clivis: two joined notes, descending, marked with an arrow, here on '-li-' of 'filius', Graduale Triplex p. 47 Square notation Clivis, square notation (University of Basel) Modern transcription li- Clivis (flexa) 2 notes going down — "fi-li-us", p. 47

4. Three-note neumes

With three notes you draw small « waves ». Remember these four above all — you will meet them constantly :

Graduale Triplex A torculus: low, high, low, here on 'na-' of 'natus', Graduale Triplex p. 47 Square notation Torculus, square notation (University of Basel) Modern transcription na- Torculus low · high · low — "na-tus", p. 47
Graduale Triplex A porrectus: high, low, high, drawn as a single curved stroke, here on '-bis' of 'nobis', Graduale Triplex p. 44 Square notation Porrectus, square notation (University of Basel) Modern transcription bis Porrectus high · low · high, one curved stroke — "no-bis", p. 44
Graduale Triplex A scandicus: notes climbing in a staircase, marked with an arrow, here on 'ho-' of 'hodie', Graduale Triplex p. 49 Square notation Scandicus, square notation (University of Basel) Modern transcription ho- Scandicus notes going up — "ho-die", p. 49
Graduale Triplex A climacus: a high note then descending notes, marked with an arrow, here on '-rit' of 'erit', Graduale Triplex p. 45 Square notation Climacus, square notation (University of Basel) Modern transcription rit Climacus 1 note then a descent — "e-rit", p. 45

5. Two signs that change the colour of the chant

Some small signs do not change the note, but the way it is sung. Here are two essential ones, which we shall meet again in the examples :

Graduale Triplex A quilisma: a zigzag-ornamented note within an ascending group, here on 'De-' of 'Dei', Graduale Triplex p. 48 Square notation Quilisma, square notation (University of Basel) Modern transcription De- Quilisma light note, springboard — "De-i", p. 48
Graduale Triplex An episema: a small horizontal stroke above a neume marking a leaning, same passage as the quilisma above, Graduale Triplex p. 48 Square notation Episema settle / broaden — "De-i", p. 48
Key point

A neume = a drawing read from left to right and from bottom to top. Its shape tells the movement of the voice ; a few added signs (episema, quilisma) tell the manner. You now have all the basic vocabulary needed to tackle the book that brings them together.
