Reciting tone

[citation needed] These include the accentus prayers and lessons chanted by the deacons or priests such as the Collect, Epistle, Gospel, Secret, Preface, Canon, and Postcommunion, as well as such regular texts as the Pater noster, Te Deum, and the Gloria in excelsis Deo.

They are also sung in versicles and responds such as the Dominus vobiscum ("The Lord be with you") of the officiant followed by the Et cum spiritu tuo ("and with your spirit") of the choir.

Each psalm tone has a formulaic intonation, mediant (or mediation), and termination (or ending).

The intonation defines the notes for the first two or three syllables, with subsequent words sung on the reciting tone.

[citation needed] The psalm verse and "Gloria Patri" (doxology) which are sung as part of the Introit (and optionally the Communion antiphon) of the Mass and of the greater responsories of the Office of Readings (Matins) and the reformed offices of Lauds and Vespers are also sung to similar sets of reciting tones that depend on the musical mode.
