Tract (literature)

A tract is a literary work, and in current usage, usually religious in nature. The notion of what constitutes a tract has changed over time. By the early part of the 21st century, these meant small pamphlets used for religious and political purposes, though far more often the former. They are often either left for someone to find or handed out. However, there have been times in history when the term implied tome-like works.

Tract (liturgy)

The tract ( Latin: tractus) is part of the proper of the liturgical celebration of the Eucharist for many Christian denominations, which is used instead of the Alleluia during Lenten or pre-Lenten seasons, in a Requiem Mass, and on a few other penitential occasions, when the joyousness of an Alleluia is deemed inappropriate. Tracts are not, however, necessarily sorrowful.

The name apparently derives from either the drawn-out style of singing or the continuous structure without a refrain. There is evidence, however, that the earliest performances were sung responsorially, and it is probable that these were dropped at an early age.

In their final form, tracts are a series of psalm verses; rarely a complete psalm, but all of the verses from the same psalm. They are restricted to only two modes, the second and the eighth. The melodies follow centonization patterns more strongly than anywhere else in the repertoire; a typical tract is almost exclusively a succession of such formulas. The cadences are nearly always elaborate melismas. Tracts with multiple verses are some of the longest chants in the Liber Usualis.
