Is transposing songs to your vocal range more octave based or pitch based? What I'm asking is can you transpose songs up or down an octave or are you looking to transpose to a different pitch within the octave its already written in? I posted a question a few days ago and didn't get a clear answer or maybe I just didn't interpret the answer or ask the question right. Below is the link to the question:
Transpose Songs To Fit My Vocal Range
What do they mean by accompaniment?
