Am I arranging? I so want Vampire Weekend Horchata as my holiday song that I found some piano vocal guitar music, just a simple melody line, and I’m figuring it out on the uke with chord melody, or what I understand of it. Same key, just adding chord bits. I sure Andrew could do a million times better but I have a tune if I can execute it. Is this called arranging or is it cheating somehow? Should one arrange from scratch? 🙂
