AD LIBITUM. - It is an expression that has various uses in the liturgy. With regard to the "Rubrics" it refers to the free use of certain "Collects" (v.). Musically it concerns individual or collective recitative chants: individual, such as certain tones of the Prayers, Epistles, Gospels, Lessons; collective, such as the various common tones of the Ordinarium Missae, like the Kyrie, Gloria, Sanctus, Agnus, and also the Credo. In ancient times even the choice of the alleluia "Sicut volueris" was synonymous with a. l. In Ambrosian chant there are on certain days some longer "melismas" or "iubilus," to be used a. l. in the case of greater solemnity. In the interpretation of certain neumes, such as the "stroficus," the a. l. may also be allowed for the greater convenience of the choir. Guido d'Arezzo considered certain neumes a. l., although he affirmed that in practice it was better to perform them.
