The Judaica stores by my house have lots of Ashkenazi music books written in sheet music, but nothing for Sephardic music. Does anyone know of any websites or titles of music books for Mizrahi style Sephardic music? I'm more interested in the music of the prayers, but any music books will do for the moment.
You can try Offtonic NusachDB. I'm not sure what you're looking for specifically, but I've added lots of Sephardic/Mizrahi transcriptions there.
