### 2.9.1 Overview of the supported styles

Three styles are available for typesetting Gregorian chant:

- Editio Vaticana is a complete style for Gregorian chant, following the appearance of the Solesmes editions, the official chant books of the Vatican since 1904. LilyPond has support for all the notational signs used in this style, including ligatures, custodes, and special signs such as the quilisma and the oriscus.
- The Editio Medicaea style offers certain features used in the Medicaea (or Ratisbona) editions which were used prior to the Solesmes editions. The most significant differences from the Vaticana style are the clefs, which have downward-slanted strokes, and the note heads, which are square and regular.
- The Hufnagel (“horseshoe nail”) or Gothic style mimics the writing style in chant manuscripts from Germany and Central Europe during the middle ages. It is named after the basic note shape (the virga), which looks like a small nail.

Three styles emulate the appearance of late-medieval and renaissance manuscripts and prints of mensural music:

- The Mensural style most closely resembles the writing style used in late-medieval and early renaissance manuscripts, with its small and narrow, diamond-shaped note heads and its rests which approach a hand-drawn style.
- The Neomensural style is a modernized and stylized version of the former: the note heads are broader and the rests are made up of straight lines. This style is particularly suited, e.g., for incipits of transcribed pieces of mensural music.
- The Petrucci style is named after Ottaviano Petrucci (1466-1539), the first printer to use movable type for music (in his Harmonice musices odhecaton, 1501). The style uses larger note heads than the other mensural styles.

Baroque and Classical are not complete styles but differ from the default style only in some details: certain note heads (Baroque) and the quarter rest (Classical).

Only the mensural style has alternatives for all aspects of the notation. Thus, there are no rests or flags in the Gregorian styles, since these signs are not used in plainchant notation, and the Petrucci style has no flags or accidentals of its own.

Each element of the notation can be changed independently of the others, so that one can use mensural flags, petrucci note heads, classical rests and vaticana clefs in the same piece, if one wishes.
