Tirzah is a girl's name in Hebrew and means : " she is my delight" or simply "delight, pleasantness".  

In John Zorn's Masada Book, a song is called "Tirzah" and on the sheet-music Zorn writes as an English subtitle : "queen of the moon".  The song Tirzah is recorded on the second Masada studio-album Beit and on the double-CD "Live in Jerusalem". It is both covered by The Cracow Klezmer Band and by Pachora.  

It occurs in the Bible as one of the daughters of Zelophehad. Also in the Song of Salomon 6:4 : "You are as beautiful as Tirzah, my darling, as lovely as Jerusalem, as majestic as troops with banners".

The name Tirzah is also to be found in the mythology of William Blake (an artist of which Zorn is fond) e.g. in the poem "To Tirzah".  

In Holland and Belgium the name rings a bell because of a best-selling and prize-winning novel by Arnon Grunberg.
