Nusach for Chazaras haSha"tz on Tishŋa b'Av

Are you asking about the words said (גרסאות) or about the tunes used?

Attached is the Dutch melody for the Kerovos of Tisho B'av. We use it in KAYJ.

(They were recorded by Rav Aharon Schuster, who was the Rov of Holland).

And here is the general melody used in Tisha B'av (Arvis and Shacharis). Recorded by Rav Aharon Schuster.

Here are two more recordings made by R' Avrohom Rogin of KAJ WH. The first is of Nachem (according to Chazzan Frankel) and the second of Aneinu. Aneinu is used in this melody on all fasts (Shacharis and Mincho, and on Tisha B'av Mincho, but not Shacharis - then the regular sad tune of the Davening is used for Aneinu too).

[Please note that instead of Hashem he says "Adoloy"].
