The Beth Gazo book is the primary reference to West Syriac liturgical music. The Beth Gazo Portal provides the text of the Syriac book of Beth Gazo along with recordings by various chanters. A database back-end allows adding new texts and audio recordings without the need to update the app. The settings allow the user to choose a default chanter and to set Garshuni preferences.

The primary text is based on a forthcoming edition of the Beth Gazo by George A. Kiraz which is based on comparing the first Deir al-Zaʿfaran edition (1908), the Dolabani edition (1913), the Çiçek edition (1985), and the audio recordings of Patr. Jacob III (1960), taking into consideration the Received Tradition.
