What's is voice leading and how does it work? I'd really appreciate a thorough answer. What I mean by how it works is how is it achieved and what's the basis of it?
Voice leading is where you write harmony as if you have several instruments, each playing an interesting melody (or at least playing a line that, although it may be boring sometimes, is not UN-melodic, leaping all over the place). The voices, in combination, form chords, but you're not just plonking down one chord after another.
