I once heard someone identifying as a "Yeki", or something like that, and the "Yekis" apparently have an interesting musical tradition where they use a different Yigdal tune before Kiddush at each festival, as well as having a special tune for festival Kiddush. But since I only heard this and never seen it written, it's a bit difficult to find out who the "Yekis" are, if I even managed to spell it correctly. Anyone know? Thank you!
Yekke Jews are of German ancestry.
They have a number of very strong traditions that set them a bit apart from the rest of "Ashkenazi" Jewry, including, but not limited to, young men wearing a Tallith Gadol prior to marriage, and slightly different cantillation tunes than most Ashkenazim.
