The meaning of todah in the title of Psalm 100

The mention of todah in the title of Ps 100 is generally interpreted as an indication of its nature as a song of confession or thanksgiving. However, in light of the use of todah to designate half-choirs in Neh 12, the article considers whether this term is introduced in the title of Ps 100 as a musical instruction for antiphonal performance. This assumption is supported by the musical context of the psalm and by indications of antiphony. It is confirmed by the division of this psalm into two parallel parts (vv. 1-3 and 4-5), and by the coherent text which emerges from the pairing of corresponding segments from these two parts, which suggest that the two voices in the dialogue were edited separately.
