You can find my arrangements (sheet music and Tabs) of these two pieces here: https://shop.per-olovkindgren.....com/?product_tag=end
These tiny "preludes" by Francesco Tárrega are not only beautiful but also rather easy to play. Endecha means "Lament". Oremus (Latin: "Let us pray") is the invitation to pray, said before short prayers in the Roman Catholic Mass and the Lutheran Divine Service.
There is no documentation that they should be played together or in what order, but many play them together often (but not always) with "Endecha" first.
In "Oremus", I added a few bass notes (the open drop D) as I think it sounds better and is easier to play plus that I think it is strange that Tárrega uses a Drop-D tuning only for the very last note... I hope you agree with me.
